Pull networking changes from David Miller:
 "Ok, we should be good to go now"

1) We have to statically initialize the init_net device list head rather
   than do so in an initcall, otherwise netprio_cgroup crashes if it's
   built statically rather than modular (Mark D.  Rustad)

2) Fix SKB null oopser in CIPSO ipv4 option processing (Paul Moore)

3) Qlogic maintainers update (Anirban Chakraborty)

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  net: Statically initialize init_net.dev_base_head
  MAINTAINERS: Changes in qlcnic and qlge maintainers list
  cipso: don't follow a NULL pointer when setsockopt() is called
