Pull networking fixes from David Miller:

 1) Provide device string properly for USB i2400m wimax devices, also
    don't OOPS when providing firmware string.  From Phil Sutter.

 2) Add support for sh_eth SH7734 chips, from Nobuhiro Iwamatsu.

 3) Add another device ID to USB zaurus driver, from Guan Xin.

 4) Loop index start in pool vector iterator is wrong causing MAC to not
    get configured in bnx2x driver, fix from Dmitry Kravkov.

 5) EQL driver assumes HZ=100, fix from Eric Dumazet.

 6) Now that skb_add_rx_frag() can specify the truesize increment
    separately, do so in f_phonet and cdc_phonet, also from Eric
    Dumazet.

 7) virtio_net accidently uses net_ratelimit() not only on the kernel
    warning but also the statistic bump, fix from Rick Jones.

 8) ip_route_input_mc() uses fixed init_net namespace, oops, use
    dev_net(dev) instead.  Fix from Benjamin LaHaise.

 9) dev_forward_skb() needs to clear the incoming interface index of the
    SKB so that it looks like a new incoming packet, also from Benjamin
    LaHaise.

10) iwlwifi mistakenly initializes a channel entry as 2GHZ instead of
    5GHZ, fix from Stanislav Yakovlev.

11) Missing kmalloc() return value checks in orinoco, from Santosh
    Nayak.

12) ath9k doesn't check for HT capabilities in the right way, it is
    checking ht_supported instead of the ATH9K_HW_CAP_HT flag.  Fix from
    Sujith Manoharan.

13) Fix x86 BPF JIT emission of 16-bit immediate field of AND
    instructions, from Feiran Zhuang.

14) Avoid infinite loop in GARP code when registering sysfs entries.
    From David Ward.

15) rose protocol uses memcpy instead of memcmp in a device address
    comparison, oops.  Fix from Daniel Borkmann.

16) Fix build of lpc_eth due to dev_hw_addr_rancom() interface being
    renamed to eth_hw_addr_random().  From Roland Stigge.

17) Make ipv6 RTM_GETROUTE interpret RTA_IIF attribute the same way
    that ipv4 does.  Fix from Shmulik Ladkani.

18) via-rhine has an inverted bit test, causing suspend/resume
    regressions.  Fix from Andreas Mohr.

19) RIONET assumes 4K page size, fix from Akinobu Mita.

20) Initialization of imask register in sky2 is buggy, because bits are
    "or'd" into an uninitialized local variable.  Fix from Lino
    Sanfilippo.

21) Fix FCOE checksum offload handling, from Yi Zou.

22) Fix VLAN processing regression in e1000, from Jiri Pirko.
