pktgen: allow faster module unload
Unloading pktgen module needs ~6 seconds on a 64 cpus machine, to stop
64 kthreads.
Add a pktgen_exiting variable to let kernel threads die faster, so that
kthread_stop() doesnt have to wait too long for them. This variable is
not tested in fast path.
Note : Before exiting from pktgen_thread_worker(), we must make sure
kthread_stop() is waiting for this thread to be stopped, like its done
in kernel/softirq.c

filter: optimize sk_run_filter
Remove pc variable to avoid arithmetic to compute fentry at each filter
instruction. Jumps directly manipulate fentry pointer.
As the last instruction of filter[] is guaranteed to be a RETURN, and
all jumps are before the last instruction, we dont need to check filter
bounds (number of instructions in filter array) at each iteration, so we
remove it from sk_run_filter() params.
On x86_32 remove f_k var introduced in commit 57fe93b374a6b871
(filter: make sure filters dont read uninitialized memory)
Note : We could use a CONFIG_ARCH_HAS_{FEW|MANY}_REGISTERS in order to
avoid too many ifdefs in this code.
This helps compiler to use cpu registers to hold fentry and A
accumulator.
On x86_32, this saves 401 bytes, and more important, sk_run_filter()
runs much faster because less register pressure (One less conditional
branch per BPF instruction)

netfilter: allow hooks to pass error code back up the stack
SELinux would like to pass certain fatal errors back up the stack. This patch
implements the generic netfilter support for this functionality.

e1000e: 82574 intermittently fails to initialize with manageability f/w
The driver can fail initializing the hardware when manageability firmware
is performing concurrent MDIO operations because the hardware semaphore
scheme to prevent concurrent operations between software and firmware is
incorrect for 82574/82583. Instead of using the SWSM register, the driver
should be using the EXTCNF_CTRL register. A software mutex is also added
to prevent simultaneous software threads from performing similar concurrent
accesses.

e1000e: 82571 SerDes link handle null code word from partner
SerDes Link detection on certain 82571 mezzanine cards can fail when the
link is forced, the link partner does not recognize forced link and the
link partner sends null code words. Detect the null code words and return
to auto-negotiation state which causes the link partner to begin responding
with valid code words. Within a reasonable interval the link will finally
settle as forced by both partners.

ixgbevf: Fix Oops
The driver is calling netif_carrier_off and netif_tx_stop_all_queues
before the netdevice is registered which causes an Oops. Move call
to netif_carrier_off after the netdevice is registered and remove
call to netif_tx_stop_all_queues because there aren't any TX
queues yet.
