Pull networking fixes from David Miller:
 "Several small bug fixes all over:

   1) be2net driver uses wrong payload length when submitting MAC list
      get requests to the chip.  From Sathya Perla.

   2) Fix mwifiex memory leak on driver unload, from Amitkumar Karwar.

   3) Prevent random memory access in batman-adv, from Marek Lindner.

   4) batman-adv doesn't check for pskb_trim_rcsum() errors, also from
      Marek Lindner.

   5) Fix fec crashes on rapid link up/down, from Frank Li.

   6) Fix inner protocol grovelling in GSO, from Pravin B Shelar.

   7) Link event validation fix in qlcnic from Rajesh Borundia.

   8) Not all FEC chips can support checksum offload, fix from Shawn
      Guo.

   9) EXPORT_SYMBOL + inline doesn't make any sense, from Denis Efremov.

  10) Fix race in passthru mode during device removal in macvlan, from
      Jiri Pirko.

  11) Fix RCU hash table lookup socket state race in ipv6, leading to
      NULL pointer derefs, from Eric Dumazet.

  12) Add several missing HAS_DMA kconfig dependencies, from Geert
      Uyttterhoeven.

  13) Fix bogus PCI resource management in 3c59x driver, from Sergei
      Shtylyov.

  14) Fix info leak in ipv6 GRE tunnel driver, from Amerigo Wang.

  15) Fix device leak in ipv6 IPSEC policy layer, from Cong Wang.

  16) DMA mapping leak fix in qlge from Thadeu Lima de Souza Cascardo.

  17) Missing iounmap on probe failure in bna driver, from Wei Yongjun."
