vxlan dev currently ignores lowerdev's gso_max_size, which adversely
affects TSO performance of liquidio if it's the lowerdev. Egress TCP
packets' skb->len often exceed liquidio's advertised gso_max_size. This
may happen on other NIC drivers.
Fix it by assigning lowerdev's gso_max_size to that of vxlan dev. Might as
well do likewise for gso_max_segs.

every packet, even if the SOCK_TIMESTAMP flag is not set in the

If selinux is enabled, this cause a cache miss for every packet
since sk->sk_stamp and sk->sk_security share the same cacheline.
With this change sk_stamp is set only if the SOCK_TIMESTAMP
flag is set, and is cleared for the first packet, so that the user
perceived behavior is unchanged.
This gives up to 5% speed-up under udp-flood with small packets.

Some device drivers reset their stats at down/up events, possibly
fooling bonding stats, since they operate with relative deltas.
It is nearly not possible to fix drivers, since some of them compute the
tx/rx counters based on per rx/tx queue stats, and the queues can be
reconfigured (ethtool -L) between the down/up sequence.
Lets avoid accumulating 'negative' values that render bonding stats
useless.
It is better to lose small deltas, assuming the bonding stats are
fetched at a reasonable frequency.

40GbE Intel Wired LAN Driver Updates 2017-03-29
This series contains updates to i40e and i40evf only.
Preethi changes the default driver mode of operation to descriptor
write-back for VF.
Alex cleans up and addresses several issues in the way that i40e handles
private flags. Modifies the driver to use the length of the packet
instead of the DD status bit to determine if a new descriptor is ready
to be processed. Refactors the driver by pulling the code responsible
for fetching the receive buffer and synchronizing DMA into a single
function. Also pulled the code responsible for handling buffer
recycling and page counting and distributed it through several functions,
so we can commonize the bits that handle either freeing or recycling the
buffers. Cleans up the code in preparation for us adding support for
build_skb(). Changed the way we handle the maximum frame size for the
receive path so it is more consistent with other drivers.
Paul enables XL722 to use the direct read/write method since it does not
support the AQ command to read/write the control register.
Christopher fixes a case where we miss an arq element if a new one is
added before we enable interrupts and exit the loop.
Jake cleans up a pointless goto statement. Also cleaned up a flag that
was not being used.
Carolyn does round 2 for adding a delay to the receive queue to

This series adds support for offloading modifications of packet headers using
ConnectX-5 HW header re-write as an action applied during packet steering.
The offloaded SW mechanism is TC's pedit action. The offloading is
supported for E-Switch steering of VF traffic in the SRIOV
switchdev mode and for NIC (non eswitch) RX.
One use-case for this offload on virtual networks, is when the hypervisor
implements flow based router such as Open-Stack's DVR, where L2 headers
of guest packets re-written with routers' MAC addresses and the IP TTL
is decremented.
Another use case (which can be applied in parallel with routing) is
stateless NAT where guest L3/L4 headers are re-written.
The series is built as follows: the 1st six patches are preperations which
don't yet add new functionality, patches 7-8 add the FW APIs (data-structures
and commands) for header re-write, and patch nine allows offloading driver
to access pedit keys.
The 10th patch is somehow the core of the series, where we translate from
the pedit way to represent set of header modification elements to the FW
API for that same matter.
Once a set of HW modification is established, we register it with the FW
and get a modify header ID. When this ID is used with an action during
packet steering, the HW applies the header modification on the packet.
Patches 11 and 12 implement the above logic as an offload for pedit action
for the NIC and E-Switch use-cases.
I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing
and helping me testing this functionality on HW simulator, before it could
be done with FW.

- descend into drivers/net/phy/ unconditionally
- make mdiobus_setup_mdiodev_from_board_info() take a callback argument
which allows us not to expose the internal MDIO board info list and
mutex, yet maintain the logic within the same file
- relocate the code that creates a MDIO device into

- build mdio-boardinfo.o into the kernel as soon as MDIO_DEVICE is

This patch changes the way we handle the maximum frame size for the Rx
path. Previously we were rounding up to 2K for a 1500 MTU and then brining
the max frame size down to MTU plus a fixed amount. With this patch
applied what we now do is limit the maximum frame to 1.5K minus the value
for NET_IP_ALIGN for standard MTU, and for any MTU greater than 1500 we
allow up to the maximum frame size. This makes the behavior more
consistent with the other drivers such as igb which had similar logic. In
addition it reduces the test matrix for MTU since we only have two max
frame sizes that are handled for Rx now.

As far as the page count tracking one change to the logic is that

then the responsibility of the function that pulls the data to either
increment the pagecnt_bias if the buffer can be recycled as-is, or to
update page_offset so that we are pointing at the correct location for
placement of the next buffer.

The goto found here for when in MFP mode is pointless. It jumps to the
end of a series of if blocks. However, right after this statement is
a closing '}' for this if block, which will result in the program flow
going to the exact same location as the goto statement indicates. Thus,
regardless of whether we are in MFP mode, the program flow will resume
from the same location.
This arose due to various refactoring which did not notice that this
goto became essentially a no-op.
To properly understand this diff you will need to view a larger context
than is given by default.

This patch cleans up and addresses several issues in the way that i40e
handles private flags. Previously the code was choosing fixed bits and
trying to match them up with strings in a somewhat haphazard way. This
resulted in the possibility for adding a new bit and causing a mismatch as
the private flags are linear bits starting at 0, and the private flags in
the driver were split up over a group specific to the PF and a group that
was global.
What this change does is define an array of structs used to represent the
private flags. Contained within the structs are the bits necessary to know
which flags to set and/or clear depending on the state of the bit. By
doing this we can add new bits in the future with minimal overhead and
avoid creating possible mis-matches should we need to remove a flag based
on compile options.

declaration of dsa_switch_tree and netdev_set_default_ethtool_ops()
function, which is what netdevice.h requires.
No longer having dsa.h in netdevice.h means the includes in dsa.h no
longer get included. This breaks a few other files which depend on
these includes. Add these directly in the affected file.

====================
netconf: Add support for RTM_DELNETCONF
netconf notifications are sent as devices register but not when they
are deleted leaving userspace caches out of sync. Add support for
RTM_DELNETCONF to ipv4, ipv6 and mpls.
MPLS is missing RTM_NEWNETCONF as devices are created, so add it as well.

Send netconf notifications for MPLS when the device registers and
unregisters.

Refactor mpls_netconf_notify_devconf to take the event as an input arg.

Send RTM_DELNETCONF notifications when a device is deleted. The message only
needs the device index, so modify inet6_netconf_fill_devconf to skip devconf
references if it is NULL.
Allows a userspace cache to remove entries as devices are deleted.
