Emil Tantilov 9cba434f63 ixgbevf: add support for reporting RSS key and hash table for X550
This patch extends the reporting of the RSS key and hash table by
adding support for X550 VFs. The difference is that X550 VFs have
their own registers for RSS key and indirection table, so there is
no need to query the PF.

The RSS key and indirection table are stored in the adapter structure
during the configuration of VFRSSRK and VFRETA which in turn can be
used in ethtool for reporting.

The logic for writing VFRETA is also changed to make sure that the
indirection table is reported correctly.

In addition this patch adds defines for the VFRETA entries and number
of VFRSSRK registers as well as some whitespace cleanups.

This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:

 - Packets from a VF with pvid configured which were sent with a
   different vlan were transmitted instead of being discarded.

 - FCoE traffic might not recover after a failue while there's traffic
   to another function.

In addition, this FW opens the door for the driver to implement several
new features; Specifically, this enhances the device's support for
encapsulated packets and will allow vxlan/geneve offloads to be added in
the future, as well as vlan filtering offload.

Sergei Shtylyov d8b48911fd ravb: fix ring memory allocation
The driver is written as if it can adapt to a low memory situation  allocating
less RX  skbs and TX aligned buffers than the respective RX/TX ring sizes.  In
reality  though  the driver  would malfunction in this case. Stop being overly
smart and just fail in such situation -- this is achieved by moving the memory
allocation from ravb_ring_format() to ravb_ring_init().

We leave dma_map_single() calls in place but make their failure non-fatal
by marking the corresponding RX descriptors  with zero data size which should
prevent DMA to an invalid addresses.

Daniel Pieczko ab8b1f7cf8 sfc: support cascaded multicast filters
If the workaround to support cascaded multicast filters ("workaround_26807") is
enabled, the broadcast filter and individual multicast filters are not inserted
when in promiscuous or allmulti mode.

There is a race while inserting and removing filters when entering and leaving
promiscuous mode.  When changing promiscuous state with cascaded multicast
filters, the old multicast filters are removed before inserting the new filters
to avoid duplicating packets; this can lead to dropped packets until all
filters have been inserted.

The efx_nic:mc_promisc flag is added to record the presence of a multicast
promiscuous filter; this gives a simple way to tell if the promiscuous state is
changing.

If a function is in promiscuous mode and another function has a broadcast or
 multicast filter inserted, the function in promiscuous mode won't see that
 broadcast or multicast traffic.
Most notably this breaks broadcast, which means ARP doesn't work. Less
 show-stoppingly, a function listening on a multicast address that's also in
 promiscuous mode will not see that multicast traffic if another function is
 also listening on that multicast address.

Daniel Pieczko 5a55a72abe sfc: warn if other functions have been reset by MCFW
When enabling the workaround for cascaded multicast filters, the MC
 can reset other functions if they have already inserted filters.
 In that case, the workaround has been enabled, but print an info
 message in the log recording that other functions had to be reset.

As other functions were reset, the MC will have incremented its boot
 count, so also increment the warm_boot_count on the function which
 enabled the workaround, as that function won't have received an MC
 reboot event and does not need to reset.

After creating event queue 0, check to see if the workaround is enabled,
 and enable it if necessary.  This will be called during PCI probe and
 also when coming back up after a reset.  The nic_data->workaround_26807
 will be used in the future to control the filter insertion behaviour
 based on this workaround.

Only the primary PF can enable this workaround, so tolerate an EPERM
 error and continue.  Otherwise, if any step in the checking and enabling
 of the workaround fails, the event queue must be removed.

We check that workaround is implemented before trying to enable it,
 and store the current workaround setting before trying to change it.

Stas Sergeev f8af8e6eb9 mvneta: use inband status only when explicitly enabled
The commit 898b2970e2 ("mvneta: implement SGMII-based in-band link state
signaling") implemented the link parameters auto-negotiation unconditionally.
Unfortunately it appears that some HW that implements SGMII protocol,
doesn't generate the inband status, so it is not possible to auto-negotiate
anything with such HW.

This patch enables the auto-negotiation only if explicitly requested with
the 'managed' DT property.

This patch fixes the following regression:

Stas Sergeev 868a4215be net: phy: fixed_phy: handle link-down case
fixed_phy_register() currently hardcodes the fixed PHY link to 1, and
expects to find a "speed" parameter to provide correct information
towards the fixed PHY consumer.

In a subsequent change, where we allow "managed" (e.g: (RS)GMII in-band
status auto-negotiation) fixed PHYs, none of these parameters can be
provided since they will be auto-negotiated, hence, we just provide a
zero-initialized fixed_phy_status to fixed_phy_register() which makes it
fail when we call fixed_phy_update_regs() since status.speed = 0 which
makes us hit the "default" label and error out.

Without this change, we would also see potentially inconsistent
speed/duplex parameters for fixed PHYs when the link is DOWN.

Florian Fainelli d2eac98f7d net: dsa: bcm_sf2: Do not override speed settings
The SF2 driver currently overrides speed settings for its port
configured using a fixed PHY, this is both unnecessary and incorrect,
because we keep feedback to the hardware parameters that we read from
the PHY device, which in the case of a fixed PHY cannot possibly change
speed.

This is a required change to allow the fixed PHY code to allow
registering a PHY with a link configured as DOWN by default and avoid
some sort of circular dependency where we require the link_update
callback to run to program the hardware, and we then utilize the fixed
PHY parameters to program the hardware with the same settings.

Thomas Graf ee122c79d4 vxlan: Flow based tunneling
Allows putting a VXLAN device into a new flow-based mode in which
skbs with a ip_tunnel_info dst metadata attached will be encapsulated
according to the instructions stored in there with the VXLAN device
defaults taken into consideration.

Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is
set, the packet processing will populate a ip_tunnel_info struct for
each packet received and attach it to the skb using the new metadata
dst.  The metadata structure will contain the outer header and tunnel
header fields which have been stripped off. Layers further up in the
stack such as routing, tc or netfitler can later match on these fields
and perform forwarding. It is the responsibility of upper layers to
ensure that the flag is set if the metadata is needed. The flag limits
the additional cost of metadata collecting based on demand.

This prepares the VXLAN device to be steered by the routing and other
subsystems which allows to support encapsulation for a large number
of tunnel endpoints and tunnel ids through a single net_device which
improves the scalability.

It also allows for OVS to leverage this mode which in turn allows for
the removal of the OVS specific VXLAN code.

Because the skb is currently scrubed in vxlan_rcv(), the attachment of
the new dst metadata is postponed until after scrubing which requires
the temporary addition of a new member to vxlan_metadata. This member
is removed again in a later commit after the indirect VXLAN receive API
has been removed.

Joachim Eastwood a7a6268590 stmmac: fix setting of driver data in stmmac_dvr_probe
Commit 803f8fc462 ("stmmac: move driver data setting into
stmmac_dvr_probe") mistakenly set priv and not priv->dev as
driver data. This meant that the remove, resume and suspend
callbacks that fetched and tried to use this data would most
likely explode. Fix the issue by using the correct variable.

====================
Intel Wired LAN Driver Updates 2015-07-17

This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
freescale, siena and dp83640.

Jacob provides several patches to clarify the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info().  It is okay to support
the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
filters.

Alex Duyck provides a igb patch to pull the time stamp from the fragment
before it gets added to the skb, to avoid a possible issue in which the
fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
being pulled after the copybreak check.  Also provides a ixgbevf patch to
fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
the advantage that the fragment does not have to be modified after it is
added to the skb.

Fan provides patches for ixgbe/ixgbevf to set the receive hash type
based on receive descriptor RSS type.

Todd provides a fix for igb where on check for link on any media other
than copper was not being detected since it was looking on the incorrect
PHY page (due to the page being used gets switched before the function
to check link gets executed).

Florian Fainelli 6cc8e6d4dc net: bcmgenet: Delay PHY initialization to bcmgenet_open()
We are currently doing a full PHY initialization and even starting the
pHY state machine during bcmgenet_mii_init() which is executed in the
driver's probe function. This is convenient to determine whether we can
attach to a proper PHY device but comes at the expense of spending up to
10ms per MDIO transactions (to reach the waitqueue timeout), which slows
things down.

This also creates a sitaution where we end-up attaching twice to the
PHY, which is not quite correct either.

Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
its error path accordingly.

Avoid printing the message "attached PHY at address 1 [...]" every time
we bring up/down the interface and remove this print since it duplicates
what the PHY driver already does for us.

Florian Fainelli c624f89121 net: bcmgenet: Determine PHY type before scanning MDIO bus
Our internal GPHY might be powered off before we attempt scanning the
MDIO bus and bind a driver to it. The way we are currently determining
whether a PHY is internal or not is done *after* we have successfully
matched its driver. If the PHY is powered down, it will not respond to
the MDIO bus, so we will not be able to bind a driver to it.

Our Device Tree for GENET interfaces specifies a "phy-mode" value:
"internal" which tells if this internal uses an internal PHY or not.

If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
additional manual lookup, and if we find "internal" set the
corresponding internal variable accordingly.

Replace all uses of phy_is_internal() with a check against
priv->internal_phy to avoid having to rely on whether or not
priv->phydev is set correctly.

dingtianhong a951bc1e6b bonding: correct the MAC address for "follow" fail_over_mac policy
The "follow" fail_over_mac policy is useful for multiport devices that
either become confused or incur a performance penalty when multiple
ports are programmed with the same MAC address, but the same MAC
address still may happened by this steps for this policy:

1) echo +eth0 > /sys/class/net/bond0/bonding/slaves
   bond0 has the same mac address with eth0, it is MAC1.

2) echo +eth1 > /sys/class/net/bond0/bonding/slaves
   eth1 is backup, eth1 has MAC2.

3) ifconfig eth0 down
   eth1 became active slave, bond will swap MAC for eth0 and eth1,
   so eth1 has MAC1, and eth0 has MAC2.

4) ifconfig eth1 down
   there is no active slave, and eth1 still has MAC1, eth2 has MAC2.

5) ifconfig eth0 up
   the eth0 became active slave again, the bond set eth0 to MAC1.

Something wrong here, then if you set eth1 up, the eth0 and eth1 will have the same
MAC address, it will break this policy for ACTIVE_BACKUP mode.

This patch will fix this problem by finding the old active slave and
swap them MAC address before change active slave.

Florian Fainelli b8c6cd1d31 net: dsa: bcm_sf2: do not use indirect reads and writes for 7445E0
7445E0 contains an ECO which disconnected the internal SF2 pseudo-PHY which was
known to conflict with the external pseudo-PHY of BCM53125 switches. This
motivated the need to utilize the internal SF2 MDIO controller via indirect
register reads/writes to control external Broadcom switches due to this address
conflict (both responded at address 30d).

For 7445E0, the internal pseudo-PHY of the SF2 switch got disconnected, and as
a consequence this prevents the internal SF2 MDIO bus controller from reading
data (reads back everything as 0) since the MDI line is tied low.

Fix this by making the indirect register reads and writes conditional to
7445D0, on 7445E0 we can utilize the SWITCH_MDIO controller (backed by
mdio-unimac and not the DSA created slave MII bus).

We utilize of_machine_is_compatible() here since this is the only way for use
to differentiate between these two chips in a way that does not violate layers
or becomes (too) vendor-specific.

Nikolay Aleksandrov 7d5cd2ce52 bonding: correctly handle bonding type change on enslave failure
If the bond is enslaving a device with different type it will be setup
by it, but if after being setup the enslave fails the bond doesn't
switch back its type and also keeps pointers to foreign structures that can
be long gone. Thus revert back any type changes if the enslave failed and
the bond had to change its type.
Example:
 Before patch:
$ echo lo > bond0/bonding/slaves
-bash: echo: write error: Cannot assign requested address
$ ip l sh bond0

$ echo +eth1 > bond0/bonding/slaves
$ ip l sh bond0
20: bond0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
    link/ether 52:54:00:3f:47:69 brd ff:ff:ff:ff:ff:ff
(notice the MASTER flag is gone)

 After patch:
$ echo lo > bond0/bonding/slaves
-bash: echo: write error: Cannot assign requested address
$ ip l sh bond0

Thus remove the proc entry manually if bond_release_and_destroy() is
used. Because of the checks in bond_remove_proc_entry() it's not a
problem for a bond device to change namespaces (the bug fixed by the
Fixes commit) but since commit
f939981492 ("bonding: Don't allow bond devices to change network
namespaces.") that can't happen anyway.

Vivien Didelot 40a7166044 net: dsa: mv88e6xxx: fix fid_mask when leaving bridge
The mv88e6xxx_priv_state structure contains an fid_mask, where 1 means
the FID is free to use, 0 means the FID is in use.

This patch fixes the bit clear in mv88e6xxx_leave_bridge() when
assigning a new FID to a port.

Example scenario: I have 7 ports, port 5 is CPU, port 6 is unused (no
PHY). After setting the ports 0, 1 and 2 in bridge br0, and ports 3 and
4 in bridge br1, I have the following fid_mask: 0b111110010110 (0xf96).

Indeed, br0 uses FID 0, and br1 uses FID 3.

After setting nomaster for port 0, I get the wrong fid_mask: 0b10 (0x2).

With this patch we correctly get 0b111110010100 (0xf94), meaning port 0
uses FID 1, br0 uses FID 0, and br1 uses FID 3.

Govindarajulu Varadarajan d9382bda4e enic: allow adaptive coalesce setting for msi/legacy intr
* Allow setting of adaptive coalescing setting for all types of interrupt.

* In msi & legacy intr, we use single interrupt for rx & tx. In this case
  tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs.
  Do not display tx_coal values for msi/intx. And do not allow user to set
  this as well.

* Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings.
  For other values, driver does not return error. So ethtool succeeds for
  unsupported values. Introduce enic_coalesce_valid() function to validate
  the coalescing values.

* If user requests for coalesce value greater than what adaptor supports,
  driver uses the max value. We should at least log this.

For two reasons I want to disable this:
1. Not any part actually check the report status(Alexander Duyck)
2. To report hash value of a packet to stack,
   RSS -> 32bits hash value
   Perfect match fdir filter -> 13bits hash value
   Hashed-based fdir filter -> 31bits hash value

   fdir filter might hash on masked tuples for IP address,
   so it's still not desirable for usage.

So for now, just stick to RSS 32bits hash value.

Alexander Duyck f56e7bba22 igb: Pull timestamp from fragment before adding it to skb
This change makes it so that we pull the timestamp from the fragment before
we add it to the skb.  By doing this we can avoid a possible issue in which
the fragment can possibly be less than IGB_RX_HDR_LEN due to the timestamp
being pulled after the copybreak check.

While making this change I realized we could also pull the rest of the
igb_pull_tail function into igb_add_rx_frag since in the case of igb,
unlike ixgbe, we are able to unmap the entire buffer before calling
add_rx_frag so merging the two allows for sharing of code between the two
merged functions.

First, dma_sync_single_for_cpu() shouldn't have been called in the first place
(it's a streaming DMA API), dma_unmap_single() should have been called instead.
Second, dma_unmap_single() call after handing the buffer to napi_gro_receive()

If a valid power regulator or a dummy regulator is used (which
happens to be the case when no regulator is specified), restart_work
is queued no matter whether the device was running or not at suspend
time. Since work queues get initialized in the ndo_open callback,
resuming leads to a NULL pointer exception.

Reverse exactly the steps executed at suspend time:
- Enable the power regulator in any case
- Enable the transceiver regulator if the device was running, even in
  case we have a power regulator
- Queue restart_work only in case the device was running

Konstantin Khlebnikov 6640e673c6 ipvlan: unhash addresses without synchronize_rcu
All structures used in traffic forwarding are rcu-protected:
ipvl_addr, ipvl_dev and ipvl_port. Thus we can unhash addresses
without synchronization. We'll anyway hash it back into the same
bucket: in worst case lockless lookup will scan hash once again.

Haiyang Zhang 2de8530ba0 hv_netvsc: Add close of RNDIS filter into change mtu call
The current change mtu call only stops tx before removing RNDIS filter.
In case ringbufer is not empty, the rndis_filter_device_remove() may
hang on removing the buffers.

This patch adds close of RNDIS filter before removing it, also a
gradual waiting loop until the ring is empty. The change_mtu hang
issue under heavy traffic is solved by this patch.

Intel Wired LAN Driver Updates 2015-07-14

This series contains updates to i40e and i40evf only.

Joe Stringer and Jesse Gross add a ndo_features_check function to ensure
that the i40e driver does not try to offload packets that exceed 80 bytes
in length.

Anjali adds additional stats to track flow director ATR and SB current
state and flow director flush count which will help the need for verbose
debug logs with respect to flow director.  Also refines an error message
to avoid confusion, so that it indicates what may have really happened
when the init_shared_code() call possibly fails.

Pawel adds new fields to the capabilities structures to handle Flex-10
device/function capabilities which is needed to support Flex-10 configs.

Jesse improves the transmit performance by added a prefetch for the
next transmit descriptor to be used when we know there are more coming.

Mitch modifies i40evf driver to handle/allow an abundance of vectors.
Currently the driver only maps transmit and receive queues to a single
MSI-X vector per queue if there are exactly enough vectors for this, but
if we have too many vectors, it will fail and allocate queues to vectors
in a suboptimal manner.  So change the condition check to allow for an
excess number of vectors and won't use the extras.  Also update the
driver to just return success if the user attempts to set a port VLAN on
a VF that already has the same port VLAN configured, instead of going
through unnecessary filter removals & adds.  Fix the MAC filters for VFs,
which were being programmed with 0 for the VLAN value when there was no
VLAN assigned.  Instead, we must use -1 to indicate that no VLAN is in
use.  Fix the VF disable code, which was not properly cleaning up the VF
and would leave the VF in an indeterminate state, so fix this by
notifying the VF and then call the normal VF reset routine.  Fix the
logic in the driver so that MAC filters are added and removed correctly
and added a check for the driver's hardware MAC address so that this
filter does not get removed incorrectly.

Carolyn removes incorrect #ifdef's which should not have been added in
the first place and with the #ifdef's removed, make the necessary
changes in the driver to resolve compile errors.

Greg updates the admin queue command header defines.

v2: fix indentation in patch 12 based on feedback from Sergei Shtylyov
