When turning off ntuple with a FD table full situation,
the driver would have auto disabled FD filter additions.
Clear the auto disable flag for FD_SB so that when the
feature is turned on again using "ethtool -K ethx ntuple on"
we can start adding filters once again.

The i40evf_irq_enable and i40evf_fire_sw_interrupt functions were
unfairly discriminating against MSI-X vector 0, just because it doesn't
handle traffic. That doesn't mean it's not essential to the operation of
the driver. This change allows the watchdog to fire vector 0 via
software, which makes the driver tolerant of dropped interrupts on that
vector.
Buck up, vector 0! You can be part of our gang!

If the AQ interrupt gets lost for some reason, VF communications will
stall as the VFs have no way of reaching the PF, which is essentially
deaf. The VFs end up waiting forever for a reply that will never come.
To alleviate this condition, go ahead and check the ARQ every time we
run the service task. Remove the check for a pending event, and get rid
of a chatty error message that is now meaningless.

The HW still needs to consume it and freeing it in the function
that created it would mean we will be racing with the HW. The
i40e_clean_tx_ring() routine will free up the buffer attached once
the HW has consumed it. The clean_fdir_tx_irq function had to be fixed
to handle the freeing correctly.
Cases where we program more than one filter per flow (Ipv4), the
code had to be changed to allocate dummy buffer multiple times
since it will be freed by the clean routine. This also fixes an issue
where the filter program routine was not checking if there were
descriptors available for programming a filter.

When an UDP application switches from AF_INET to AF_INET6 sockets, we
have a small performance degradation for IPv4 communications because of
extra cache line misses to access ipv6only information.
This can also be noticed for TCP listeners, as ipv6_only_sock() is also
used from __inet_lookup_listener()->compute_score()
This is magnified when SO_REUSEPORT is used.
Move ipv6only into struct sock_common so that it is available at
no extra cost in lookups.

Intel Wired LAN Driver Updates 2014-07-01
This series contains updates to i40e, i40evf, igb and ixgbe.
Shannon adds the Base Address High and Low to the admin queue structure
to simplify the logic in the configuration routines. Also adds code to
clear all queues and interrupts to help clean up after a PXE or other
early boot activity.
Kevin fixes mask assignment value since -1 cannot be used for unsigned
integer types.
Mitch fixes an issue where in some circumstances the reply from the PF
would come back before we were able to properly modify the admin queue
pending and required flags. This would mess up the flags and put the
driver in an indeterminate state, so fix this by simply setting the flags
before sending the request to the admin queue. Also changes the branding
string for i40evf to reduce confusion and to match up with our other
marketing materials.
Kamil adds a new variable defining admin send queue (ASQ) command write
back timeout to allow for dynamic modification of this timeout.
Anjali fix a bug in the flow director filter replay logic, so that we
call a replay after a sideband reset correctly.
Jesse adds code to initialize all members of the context descriptor to
prevent possible stale data.
Christopher fixes i40e to prevent writing to reserved bits, since the
queue index is only 0-127.
Jacob removes the unneeded header export.h from the i40e PTP code.
Fixes ixgbe PTP code where the PPS signal was not correct, as it
generates a one half HZ clock signal, it only generates one level
change per second. To generate a full clock, we need two level changes
per second.

There are linux distributions where the inbox bnx2x driver contains SRIOV
support but doesn't contain the changes introduced in b9871bcf
"bnx2x: VF RSS support - PF side".
A VF in a VM running that distribution over a new hypervisor will access
incorrect addresses when trying to transmit packets, causing an attention
in the hypervisor and making that VF inactive until FLRed.
The driver in the VM has to ne upgraded [no real way to overcome this], but
due to the HW attention currently arising upgrading the driver in the VM
would not suffice [since the VF needs also be FLRed if the previous driver
was already loaded].
This patch causes the PF to fail the acquire message from a VF running an
old problematic driver; The VF will then gracefully fail it's probe preventing
the HW attention [and allow clean upgrade of driver in VM].

The if_lock()/if_unlock() in next_to_run() adds a significant
overhead, because its called for every packet in busy loop of
pktgen_thread_worker(). (Thomas Graf originally pointed me
at this lock problem).
Removing these two "LOCK" operations should in theory save us approx
16ns (8ns x 2), as illustrated below we do save 16ns when removing
the locks and introducing RCU protection.
Performance data with CLONE_SKB==100000, TX-size=512, rx-usecs=30:
(single CPU performance, ixgbe 10Gbit/s, E5-2630)
* Prev : 5684009 pps --> 175.93ns (1/5684009*10^9)
* RCU-fix: 6272204 pps --> 159.43ns (1/6272204*10^9)
* Diff : +588195 pps --> -16.50ns
To understand this RCU patch, I describe the pktgen thread model
below.
In pktgen there is several kernel threads, but there is only one CPU
running each kernel thread. Communication with the kernel threads are
done through some thread control flags. This allow the thread to
change data structures at a know synchronization point, see main
thread func pktgen_thread_worker().
Userspace changes are communicated through proc-file writes. There
are three types of changes, general control changes "pgctrl"
(func:pgctrl_write), thread changes "kpktgend_X"
(func:pktgen_thread_write), and interface config changes "etcX@N"
(func:pktgen_if_write).
Userspace "pgctrl" and "thread" changes are synchronized via the mutex
pktgen_thread_lock, thus only a single userspace instance can run.
The mutex is taken while the packet generator is running, by pgctrl
"start". Thus e.g. "add_device" cannot be invoked when pktgen is
running/started.
All "pgctrl" and all "thread" changes, except thread "add_device",
communicate via the thread control flags. The main problem is the
exception "add_device", that modifies threads "if_list" directly.
Fortunately "add_device" cannot be invoked while pktgen is running.
But there exists a race between "rem_device_all" and "add_device"
(which normally don't occur, because "rem_device_all" waits 125ms
before returning). Background'ing "rem_device_all" and running
"add_device" immediately allow the race to occur.
The race affects the threads (list of devices) "if_list". The if_lock
is used for protecting this "if_list". Other readers are given
lock-free access to the list under RCU read sections.
Note, interface config changes (via proc) can occur while pktgen is
running, which worries me a bit. I'm assuming proc_remove() takes
appropriate locks, to assure no writers exists after proc_remove()
finish.
I've been running a script exercising the race condition (leading me
to fix the proc_remove order), without any issues. The script also
exercises concurrent proc writes, while the interface config is
getting removed.

Avoid calling set_current_state() inside the busy-loop in
pktgen_thread_worker(). In case of pkt_dev->delay, then it is still
used/enabled in pktgen_xmit() via the spin() call.
The set_current_state(TASK_INTERRUPTIBLE) uses a xchg, which implicit
is LOCK prefixed. I've measured the asm LOCK operation to take approx
8ns on this E5-2630 CPU. Performance increase corrolate with this
measurement.

Using pktgen I'm seeing the ixgbe driver "push-back", due TX ring
running full. Thus, the TX ring is artificially limiting pktgen.
(Diagnose via "ethtool -S", look for "tx_restart_queue" or "tx_busy"
counters.)
Using ixgbe, the real reason behind the TX ring running full, is due
to TX ring not being cleaned up fast enough. The ixgbe driver combines
TX+RX ring cleanups, and the cleanup interval is affected by the
ethtool --coalesce setting of parameter "rx-usecs".
Do not increase the default NIC TX ring buffer or default cleanup
interval. Instead simply document that pktgen needs special NIC
tuning for maximum packet per sec performance.
Performance results with pktgen with clone_skb=100000.
TX ring size 512 (default), adjusting "rx-usecs":
(Single CPU performance, E5-2630, ixgbe)

Notice after commit 6f25cd47d (pktgen: fix xmit test for BQL enabled
devices) pktgen uses netif_xmit_frozen_or_drv_stopped() and ignores
the BQL "stack" pause (QUEUE_STATE_STACK_XOFF) flag. This allow us to put
more pressure on the TX ring buffers.
It is the ixgbe_maybe_stop_tx() call that stops the transmits, and
pktgen respecting this in the call to netif_xmit_frozen_or_drv_stopped(txq).

veth interface pairs and/or other virtual interfaces,
and applications that can bind to interfaces and/or IP addresses,
it is possibly to create one or more virtual routers with multiple
