Ido Schimmel 808be37ae3 mlxsw: spectrum_acl: Adapt ACL configuration to new firmware versions
The driver currently creates empty ACL groups, binds them to the
requested port and then fills them with actual ACLs that point to TCAM
regions.

However, empty ACL groups are considered invalid and upcoming firmware
versions are going to forbid their binding.

Work around this limitation by only performing the binding after the
first ACL was added to the group.

Grygorii Strashko a3a41d2f94 net: ethernet: ti: cpsw: enable vlan rx vlan offload
In VLAN_AWARE mode CPSW can insert VLAN header encapsulation word on Host
port 0 egress (RX) before the packet data if RX_VLAN_ENCAP bit is set in
CPSW_CONTROL register. VLAN header encapsulation word has following format:

 HDR_PKT_Priority bits 29-31 - Header Packet VLAN prio (Highest prio: 7)
 HDR_PKT_CFI 	  bits 28 - Header Packet VLAN CFI bit.
 HDR_PKT_Vid 	  bits 27-16 - Header Packet VLAN ID
 PKT_Type         bits 8-9 - Packet Type. Indicates whether the packet is
                 	VLAN-tagged, priority-tagged, or non-tagged.
	00: VLAN-tagged packet
	01: Reserved
	10: Priority-tagged packet
	11: Non-tagged packet

This feature can be used to implement TX VLAN offload in case of
VLAN-tagged packets and to insert VLAN tag in case Non-tagged packet was
received on port with PVID set. As per documentation, CPSW never modifies
packet data on Host egress (RX) and as result, without this feature
enabled, Host port will not be able to receive properly packets which
entered switch non-tagged through external Port with PVID set (when
non-tagged packet forwarded from external Port with PVID set to another
external Port - packet will be VLAN tagged properly).

Implementation details:
- on RX driver will check CPDMA status bit RX_VLAN_ENCAP BIT(19) in CPPI
descriptor to identify when VLAN header encapsulation word is present.
- PKT_Type = 0x01 or 0x02 then ignore VLAN header encapsulation word and
pass packet as is;
- if HDR_PKT_Vid = 0 then ignore VLAN header encapsulation word and pass
packet as is;
- In dual mac mode traffic is separated between ports using default port
vlans, which are not be visible to Host and so should not be reported.
Hence, check for default port vlans in dual mac mode and ignore VLAN header
encapsulation word;
- otherwise fill SKB with VLAN info using __vlan_hwaccel_put_tag();
- PKT_Type = 0x00 (VLAN-tagged) then strip out VLAN header from SKB.

According to AM335x TRM[1] 14.3.6.2, AM437x TRM[2] 15.3.6.2 and
DRA7 TRM[3] 24.11.4.8.7.3.3, in-band mode in EXT_EN(bit18) register is only
available when PHY is configured in RGMII mode with 10Mbps speed. It will
cause some networking issues without RGMII mode, such as carrier sense
errors and low throughput. TI also mentioned this issue in their forum[4].

This patch adds the check mechanism for PHY interface with RGMII interface
type, the in-band mode can only be set in RGMII mode with 10Mbps speed.

Ido Schimmel bcdd5de80a mlxsw: spectrum_buffers: Set a minimum quota for CPU port traffic
In commit 9ffcc3725f ("mlxsw: spectrum: Allow packets to be trapped
from any PG") I fixed a problem where packets could not be trapped to
the CPU due to exceeded shared buffer quotas. The mentioned commit
explains the problem in detail.

The problem was fixed by assigning a minimum quota for the CPU port and
the traffic class used for scheduling traffic to the CPU.

However, commit 117b0dad2d ("mlxsw: Create a different trap group list
for each device") assigned different traffic classes to different
packet types and rendered the fix useless.

Fix the problem by assigning a minimum quota for the CPU port and all
the traffic classes that are currently in use.

Florian Fainelli 484d802d0f net: systemport: Rewrite __bcm_sysport_tx_reclaim()
There is no need for complex checking between the last consumed index
and current consumed index, a simple subtraction will do.

This also eliminates the possibility of a permanent transmit queue stall
under the following conditions:

- one CPU bursts ring->size worth of traffic (up to 256 buffers), to the
  point where we run out of free descriptors, so we stop the transmit
  queue at the end of bcm_sysport_xmit()

- because of our locking, we have the transmit process disable
  interrupts which means we can be blocking the TX reclamation process

- when TX reclamation finally runs, we will be computing the difference
  between ring->c_index (last consumed index by SW) and what the HW
  reports through its register

- this register is masked with (ring->size - 1) = 0xff, which will lead
  to stripping the upper bits of the index (register is 16-bits wide)

- we will be computing last_tx_cn as 0, which means there is no work to
  be done, and we never wake-up the transmit queue, leaving it
  permanently disabled

A practical example is e.g: ring->c_index aka last_c_index = 12, we
pushed 256 entries, HW consumer index = 268, we mask it with 0xff = 12,
so last_tx_cn == 0, nothing happens.

Brad Mouring 2105a5d3ac net: macb: Add phy-handle DT support
This optional binding (as described in the ethernet DT bindings doc)
directs the netdev to the phydev to use. This is useful for a phy
chip that has >1 phy in it, and two netdevs are using the same phy
chip (i.e. the second mac's phy lives on the first mac's MDIO bus)

The devicetree snippet would look something like this:

ethernet@feedf00d {
	...
	phy-handle = <&phy0> // the first netdev is physically wired to phy0
	...
	phy0: phy@0 {
		...
		reg = <0x0> // MDIO address 0
		...
	}
	phy1: phy@1 {
		...
		reg = <0x1> // MDIO address 1
		...
	}
...
}

ethernet@deadbeef {
	...
	phy-handle = <&phy1> // tells the driver to use phy1 on the
						 // first mac's mdio bus (it's wired thusly)
	...
}

Govindarajulu Varadarajan ce3db6aade enic: drop IP proto check for vxlan tunnel delete
Commit d11790941d ("enic: Add vxlan offload support for IPv6 pkts")
added vxlan offload support for IPv6 pkts. Required change in
enic_udp_tunnel_del was not made. This creates a bug where once user
adds IPv6 tunnel, hw offload for that cannot be deleted.

This patch removes check for IP proto in tunnel delete path. Driver need
not check for IP proto since same UDP port cannot be used to create two
tunnels.

Jacob Keller 089915f0f2 i40e: restore TCPv4 input set when re-enabling ATR
When we re-enable ATR we need to restore the input set for TCPv4
filters, in order for ATR to function correctly. We already do this for
the normal case of re-enabling ATR when disabling ntuple support.
However, when re-enabling ATR after the last TCPv4 filter is removed (but
when ntuple support is still active), we did not restore the TCPv4
filter input set.

This can cause problems if the TCPv4 filters from FDir had changed the
input set, as ATR will no longer behave as expected.

When clearing the ATR auto-disable flag, make sure we restore the TCPv4
input set to avoid this.

The old method with checking if port is disabled in the PRTGEN_CNF

Filip Sadowski 03ce7b1d23 i40e: Fix permission check for VF MAC filters
When VF requests adding of MAC filters the checking is done against number
of already present MAC filters not adding them at the same time. It makes
it possible to add a bunch of filters at once possibly exceeding
acceptable limit of I40E_VC_MAX_MAC_ADDR_PER_VF filters.

This happens because when checking vf->num_mac, we do not check how many
filters are being requested at once. Modify the check function to ensure
that it knows how many filters are being requested. This allows the
check to ensure that the total number of filters in a single request
does not cause us to go over the limit.

Additionally, move the check to within the lock to ensure that the
vf->num_mac is checked while holding the lock to maintain consistency.
We could have simply moved the call to i40e_vf_check_permission to
within the loop, but this could cause a request to be non-atomic, and
add some but not all the addresses, while reporting an error code. We
want to avoid this behavior so that users are not confused about which
filters have or have not been added.

we currently exit the reset routine correctly, but don't set the state to

we don't exit the reset routine at all and resetting will cause a closed
device to be opened.

10GbE Intel Wired LAN Driver Updates 2018-03-12

This series contains updates to ixgbe and ixgbevf only.

Shannon Nelson provides three fixes to the ipsec portion of ixgbe.  Make
sure we are using 128-bit authentication, since it is the only size
supported for hardware offload.  Fixed the transmit trailer length
calculation for ipsec by finding the padding value and adding it to the

transmit descriptor to tell the device where to stop the checksum

Tonghao Zhang adds a ethtool stat for receive length errors, since the
driver was already collecting this counter.

This reverts commit 4110e02eb4.
This reverts commit d3604515c9eda464a92e8e67aae82dfe07fe3c98.

Commit 19110cfbb3 ("e1000e: Separate signaling for link check/link up")
changed what happens to the link status when there is an error which
happens after "get_link_status = false" in the copper check_for_link
callbacks. Previously, such an error would be ignored and the link
considered up. After that commit, any error implies that the link is down.

Revert commit 19110cfbb3 ("e1000e: Separate signaling for link check/link
up") and its followups. After reverting, the race condition described in
the log of commit 19110cfbb3 is reintroduced. It may still be triggered
by LSC events but this should keep the link down in case the link is
electrically unstable, as discussed. The race may no longer be
triggered by RXO events because commit 4aea7a5c5e ("e1000e: Avoid
receiver overrun interrupt bursts") restored reading icr in the Other
handler.

Colin Ian King 8e8af97a3f lan743x: remove some redundant variables and assignments
Function lan743x_phy_init assigns pointer 'netdev' but this is never read
and hence it can be removed. The return error code handling can also be
cleaned up to remove the variable 'ret'.

Function lan743x_phy_link_status_change assigns pointer 'phy' twice and
this is never read, so it also can be removed.

Finally, function lan743x_tx_napi_poll initializes pointer 'adapter'
and then re-assigns the same value into this pointer a little later on
so this second assignment is redundant and can be also removed.

Petr Machata 99db5229db mlxsw: spectrum: Don't depend on ip_gre and ip6_gre
mlxsw_spectrum supports offloading of a tc action mirred egress mirror
to a gretap or an ip6gretap netdevice, which necessitates calls to
functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously
this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on
NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about
picking which modules are absolutely required, and therefore the better
approach is to make mlxsw_spectrum tolerant of absence of one or both of
the GRE flavors.

Hence rework the NET_IPGRE and IPV6_GRE dependencies to just guard
matching modularity, and hide the corresponding code in spectrum_span.c
in an #if IS_ENABLED. Mark mlxsw_sp_span_entry_tunnel_parms_common as
maybe unused, to muffle warnings if neither GRE flavor is selected,
which seems cleaner than introducing a composite #if.

Venkat Duvvuru 1a037782e7 bnxt_en: close & open NIC, only when the interface is in running state.
bnxt_restore_pf_fw_resources routine frees PF resources by calling
close_nic and allocates the resources back, by doing open_nic. However,
this is not needed, if the PF is already in closed state.

This bug causes the driver to call open the device and call request_irq()
when it is not needed.  Ultimately, pci_disable_msix() will crash
when bnxt_en is unloaded.

This patch fixes the problem by skipping __bnxt_close_nic and
__bnxt_open_nic inside bnxt_restore_pf_fw_resources routine, if the
interface is not running.

Recent changes added the bnxt_init_int_mode() call in the driver's open
path whenever ring reservations are changed.  This call was previously
only called in the probe path.  In the open path, if MQPRIO TC has been
setup, the bnxt_init_int_mode() call would reset and mess up the MQPRIO
per TC rings.

Fix it by not re-initilizing bp->tx_nr_rings_per_tc in
bnxt_init_int_mode().  Instead, initialize it in the probe path only
after the bnxt_init_int_mode() call.

Petr Machata 663f1b26f9 mlxsw: spectrum: Prevent duplicate mirrors
The Spectrum ASIC doesn't support mirroring more than once from a single
binding point (which is a port-direction pair). Therefore detect that a
second binding of a given binding point is attempted.

To that end, extend struct mlxsw_sp_span_inspected_port to track whether
a given binding point is bound or not. Extend
mlxsw_sp_span_entry_port_find() to look for ports based on the full
unique key: port number, direction, and boundness.

Besides fixing the overt bug where configured mirrors are not offloaded,
this also fixes a more subtle bug: mlxsw_sp_span_inspected_port_del()
just defers to mlxsw_sp_span_entry_bound_port_find(), and that used to
find the first port with the right number (disregarding the type). Thus
by adding and removing egress and ingress mirrors in the right order,
one could trick the system into believing it has no egress mirrors when
in fact it did have some. That then caused that
mlxsw_sp_span_port_mtu_update() didn't update mirroring buffer when MTU
was changed.

This series follows our previous one to lay out the foundations for IPSec
 in user-space and extend current kernel netdev IPSec support. As noted in
 our previous pull request cover letter "mlx5-updates-2018-02-28-1 (IPSec-1)",
 the IPSec mechanism will be supported through our flow steering mechanism.
 Therefore, we need to change the initialization order. Furthermore, IPsec
 is also supported in both egress and ingress. Since our current flow
 steering is egress only, we add an empty (only implemented through FPGA
 steering ops) egress namespace to handle that case. We also implement
 the required flow steering callbacks and logic in our FPGA driver.
 
 We extend the FPGA support for ESN and modifying a xfrm too. Therefore, we
 add support for some new FPGA command interface that supports them. The
 other required bits are added too. The new features and requirements are
 advertised via cap bits.
 
 Last but not least, we revise our driver's accel_esp API. This API will be
 shared between our netdev and IB driver, so we need to have all the required
 functionality from both worlds.

Thomas Falcon 18b8d6bbad ibmvnic: Do not disable device during failover or partition migration
During a device failover or partition migration reset, it is not
necessary to disable the backing adapter since it should not be
running yet and its Command-Response Queue is closed. Sending
device commands during this time could result in an error or
timeout disrupting the reset process. In these cases, just halt
transmissions, clean up resources, and continue with reset.

^ - marks where QP command invoked to update the SA ESN state
    machine.
| - marks the start of the ESN scope (0-2^32-1). At this point move SA
    ESN overlap bit to zero and increment ESN.

the FPGA. Each time a rule is added, the steering core infrastructure
calls the FPGA command layer. If the rule is intended for the FPGA,
it combines the IPs information with the software transformation
context and creates the respective hardware transform.
Afterwards, it calls the standard steering command layer.

Aviad Yehezkel d6c4f0298c net/mlx5: Refactor accel IPSec code
The current code has one layer that executed FPGA commands and
the Ethernet part directly used this code. Since downstream patches
introduces support for IPSec in mlx5_ib, we need to provide some
abstractions. This patch refactors the accel code into one layer
that creates a software IPSec transformation and another one which
creates the actual hardware context.
The internal command implementation is now hidden in the FPGA
core layer. The code also adds the ability to share FPGA hardware
contexts. If two contexts are the same, only a reference count
is taken.

Yossi Kuperman 788a821076 net/mlx5e: IPSec, Add support for ESP trailer removal by hardware
Current hardware decrypts and authenticates incoming ESP packets.
Subsequently, the software extracts the nexthdr field, truncates the
trailer and adjusts csum accordingly.

With this patch and a capable device, the trailer is being removed
by the hardware and the nexthdr field is conveyed via PET. This way
we avoid both the need to access the trailer (cache miss) and to
compute its relative checksum, which significantly improve
the performance.

Experiment shows that trailer removal improves the performance by
2Gbps, (netperf). Both forwarding and host-to-host configurations.

Maxime Chevallier 10fea26ce2 net: mvpp2: Add support for unicast filtering
Marvell PPv2 controller can be used to implement packet filtering based
on the destination MAC address. This is already used to implement
multicast filtering. This patch adds support for Unicast filtering.

Filtering is based on so-called "TCAM entries" to implement filtering.
Due to their limited number and the fact that these are also used for
other purposes, we reserve 80 entries for both unicast and multicast
filters. On top of the broadcast address, and each interface's own MAC
address, we reserve 25 entries per port, 4 for unicast filters, 21 for
multicast.

Whenever unicast or multicast range for one port is full, the filtering
is disabled and port goes into promiscuous mode for the given type of
addresses.

Maxime Chevallier ce2a27c761 net: mvpp2: Simplify MAC filtering function parameters
The mvpp2_prs_mac_da_accept function takes into parameter both the
struct representing the controller and the port id. This is meaningful
when we want to create TCAM entries for non-initialized ports, but in
this case we expect the port to be initialized before starting adding or
removing MAC addresses to the per-port filter.

This commit changes the function so that it takes struct mvpp2_port as
a parameter instead.

David S. Miller bcde6b725f mlx5-updates-2018-02-28-1 (IPSec-1)
This series consists of some fixes and refactors for the mlx5 drivers,
 especially around the FPGA and flow steering. Most of them are trivial
 fixes and are the foundation of allowing IPSec acceleration from user-space.
 
 We use flow steering abstraction in order to accelerate IPSec packets.
 When a user creates a steering rule, [s]he states that we'll carry an
 encrypt/decrypt flow action (using a specific configuration) for every
 packet which conforms to a certain match. Since currently offloading these
 packets is done via FPGA, we'll add another set of flow steering ops.
 These ops will execute the required FPGA commands and then call the
 standard steering ops.
 
 In order to achieve this, we need that the commands will get all the
 required information. Therefore, we pass the fte object and embed the
 flow_action struct inside the fte. In addition, we add the shim layer
 that will later be used for alternating between the standard and the
 FPGA steering commands.
 
 Some fixes, like " net/mlx5e: Wait for FPGA command responses with a timeout"
 are very relevant for user-space applications, as these applications could
 be killed, but we still want to wait for the FPGA and update the kernel's
 database.

RX rings can fit most of the time in a contiguous piece of memory,
so lets use kvzalloc_node/kvfree instead of vzalloc_node/vfree

Note that kvzalloc_node() automatically falls back to another node,
