The ELP interval and throughput override interface settings are initialized
with default settings on every time an interface is added to a mesh.
This patch prevents this behavior by moving the configuration init to the
interface detection routine which runs only once per interface.

On some platforms, syncing a buffer for DMA is expensive. Rather than
sync the whole 2K receive buffer, only synchronise the length of the
frame, which will typically be the MTU, or a much smaller TCP ACK.
For an IMX6Q, this gives around 6% increased TCP receive performance,
which is cache operations bound and reduces CPU load for TCP transmit.

alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workitem (viz
fm10k_service_task, which manages and runs other subtasks) is involved in
normal device operation and requires forward progress under memory
pressure.
create_workqueue has been replaced with alloc_workqueue with max_active
as 0 since there is no need for throttling the number of active work
items.
Since network devices may be used in memory reclaim path,
WQ_MEM_RECLAIM has been set to guarantee forward progress.
flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty. Hence the call to flush_workqueue() has been dropped.

40GbE Intel Wired LAN Driver Updates 2016-06-27
This series contains updates to i40e and i40evf only.
Mitch provides several changes, first adds functions to enable and disable
VSI on a VEB, which allows for configuration of limited promiscuous mode
specifically for bridging purposes. Sets the RSS Hash Enable registers by
default now that VF RSS is configured by the PF driver. Fixed a issue
where we could overflow the buffer, by checking the address count and bail
out of the loop at the appropriate time. Removed the need for a reset
when the device enters limited promiscuous mode, since this was causing
heartburn for people who were using VFs and bridging.
Catherine adds a call to set the client interface down when we put the VSI
down. Fixed an issue where RSS queues was being limited to the number
of CPUs, so if a user wants to use more queues than CPUs, we want to
trust they know what they are doing and let them.
Greg cleans up the driver suspend routine to ensure we are calling
synchronize_irq() before freeing IRQ vectors and explicitly free the other
causes interrupt resources and shut down the MSIX interrupt.
Serey fixes i40e_set_settings() to not fail when a Direct Attach (DA)
cable is used.
Avinash fixes a supported link bug by removing code which was not allowing
100BaseT to show up in the supported link modes for 10GBaseT PHYs.
Shannon adds a bit of information to the error messages to help determine
the source of error by adding VSI info to macaddr messages.
Tushar Dave fixes error received when turning off TSO on some systems,
which was caused by enabling FD_SB without checking availability of
MSIx vectors, so add the check.
Neerav fixes a possible panic when LLDP/DCBX change happens and the
driver tried to notify the client(s) for each of the PF VSIs, which would
panic when it reached a VSI that did not have any netdev associated with
it.

net_device already contain such pointer. So we can remove the pointer

Only the first and last netlink message for a particular conntrack are
actually sent. The first message is sent through nf_conntrack_confirm when
the conntrack is committed. The last one is sent when the conntrack is
destroyed on timeout. The other conntrack state change messages are not
advertised.
When the conntrack subsystem is used from netfilter, nf_conntrack_confirm
is called for each packet, from the postrouting hook, which in turn calls
nf_ct_deliver_cached_events to send the state change netlink messages.
This commit fixes the problem by calling nf_ct_deliver_cached_events in the
non-commit case as well.

SPQ doorbell is currently protected with the compilation barrier. Under the
stress scenarios, we may get into a state where (due to the weak ordering)
several ramrod doorbells were written to the BAR with an out-of-order
producer values. Need to change the barrier type to a write barrier to make
sure that the write buffer is flushed after each doorbell.

neigh_xmit() expects to be called inside an RCU-bh read side critical
section, and while one of its two current callers gets this right, the
other one doesn't.
More specifically, neigh_xmit() has two callers, mpls_forward() and
mpls_output(), and while both callers call neigh_xmit() under
rcu_read_lock(), this provides sufficient protection for neigh_xmit()
only in the case of mpls_forward(), as that is always called from
softirq context and therefore doesn't need explicit BH protection,
while mpls_output() can be called from process context with softirqs
enabled.
When mpls_output() is called from process context, with softirqs
enabled, we can be preempted by a softirq at any time, and RCU-bh
considers the completion of a softirq as signaling the end of any
pending read-side critical sections, so if we do get a softirq
while we are in the part of neigh_xmit() that expects to be run inside
an RCU-bh read side critical section, we can end up with an unexpected
RCU grace period running right in the middle of that critical section,
making things go boom.
This patch fixes this impedance mismatch in the callee, by making
neigh_xmit() always take rcu_read_{,un}lock_bh() around the code that
expects to be treated as an RCU-bh read side critical section, as this
seems a safer option than fixing it in the callers.

I've got a bug report about an e1000e interface, where a VLAN interface is
set up on top of it:
$ ip link add link ens1f0 name ens1f0.99 type vlan id 99
$ ip link set ens1f0 up
$ ip link set ens1f0.99 up
$ ip addr add 192.168.99.92 dev ens1f0.99
At this point, I can ping another host on vlan 99, ip 192.168.99.91.
However, if I do the following:
$ ethtool -K ens1f0 rxvlan off
Then no traffic passes on ens1f0.99. It comes back if I toggle rxvlan on
again. I'm not sure if this is actually intended behavior, or if there's a
lack of software VLAN stripping fallback, or what, but things continue to
work if I simply don't call e1000e_vlan_strip_disable() if there are
active VLANs (plagiarizing a function from the e1000 driver here) on the
interface.
Also slipped a related-ish fix to the kerneldoc text for
e1000e_vlan_strip_disable here...

The PDU length of incoming LLC frames is set to the total skb payload size
in __ieee80211_data_to_8023() of net/wireless/util.c which incorrectly
includes the length of the IEEE 802.11 header.
The resulting LLC frame header has a too large PDU length, causing the
llc_fixup_skb() function of net/llc/llc_input.c to reject the incoming
skb, effectively breaking STP.
Solve the problem by properly substracting the IEEE 802.11 frame header size
from the PDU length, allowing the LLC processor to pick up the incoming
control messages.
Special thanks to Gerry Rozema for tracking down the regression and proposing
a suitable patch.

Commit dead9f29dd ("perf: Fix race in BPF program unregister") moved
destruction of BPF program from free_event_rcu() callback to __free_event(),
which is problematic if used with tail calls: if prog A is attached as
trace event directly, but at the same time present in a tail call map used
by another trace event program elsewhere, then we need to delay destruction
via RCU grace period since it can still be in use by the program doing the
tail call (the prog first needs to be dropped from the tail call map, then
trace event with prog A attached destroyed, so we get immediate destruction).
