Pull networking fixes from David S. Miller:

This has the fix for the wireless issues I ran into the other week as
well as:

 1) Fix CAN c_can driver transmit handling resulting in BUG check
    triggers, from AnilKumar Ch.

 2) Fix packet drop monitor sleeping in atomic context, from Eric
    Dumazet.

 3) Fix mv643xx_eth driver build regression, from Andrew Lunn.

 4) Inetpeer freeing needs an RCU grace period in order to avoid races
    during tree invalidation.  From Eric Dumazet.

 5) Fix endianness bugs in xt_HMARK netfilter module, from Hans
    Schillstrom.

 6) Add proper module refcounting to l2tp_eth to avoid crash on module
    unload, from Eric Dumazet.

 7) Fix truncation of neighbour entry dumps due to logic errors in
    neigh_dump_info() and friends, from Eric Dumazet.

 8) The conversion of fib6_age() to dst_neigh_lookup() accidently
    reversed the logic of a flags test, fix from Thomas Graf.

 9) Fix checksum configuration in newer sky2 chips, from Stephen
    Hemminger.

10) Revert BQL support in NIU driver, doesn't work.

11) l2tp_ip_sendmsg() illegally uses a route without a proper reference.
    From Eric Dumazet.

12) be2net driver references an SKB after it's potentially been freed,
    also from Eric Dumazet.

13) Fix RCU stalls in dummy net driver init.  Also from Eric Dumazet.

14) lpc_eth has several bugs in it's transmit engine leading to packet
    leaks and improper queue wakes, from Eric Dumazet.

15) Apply short DMA workaround to more tg3 chips, from Matt Carlson.

16) Add tilegx network driver.

17) Bonding queue mapping for a packet can get corrupted, fix from Eric
    Dumazet.

18) Fix bug in netpoll_send_udp() SKB management that can leave garbage
    in the payload in certain situations.  From Eric Dumazet.

19) bnx2x driver interprets chip RX checksum offload incorrectly in
    encapsulation situations.  Fix from Eric Dumazet.

When one or more packets are received, an interrupt happens. The interrupts
are not queued so the driver has to scan all the descriptors in the ring during
the receive process.
This is based on NAPI so the interrupt handler signals only if there is work to be
done, and it exits.
This is based on NAPI so the interrupt handler signals only if there is work

Then the poll method will be scheduled at some future point.
The incoming packets are stored, by the DMA, in a list of pre-allocated socket
buffers in order to avoid the memcpy (Zero-copy).
4.3) Timer-Driver Interrupt
Instead of having the device that asynchronously notifies the frame receptions, the
driver configures a timer to generate an interrupt at regular intervals.
Based on the granularity of the timer, the frames that are received by the device
will experience different levels of latency. Some NICs have dedicated timer
device to perform this task. STMMAC can use either the RTC device or the TMU
channel 2 on STLinux platforms.

The timers frequency can be passed to the driver as parameter; when change it,
