Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

Pull networking fixes from David Miller:

1) GRE tunnel drivers don't set the transport header properly, they also
   blindly deref the inner protocol ipv4 and needs some checks.  Fixes
   from Isaku Yamahata.

2) Fix sleeps while atomic in netdevice rename code, from Eric Dumazet.

3) Fix double-spinlock in solos-pci driver, from Dan Carpenter.

4) More ARP bug fixes.  Fix lockdep splat in arp_solicit() and then the
   bug accidentally added by that fix.  From Eric Dumazet and Cong Wang.

5) Remove some __dev* annotations that slipped back in, as well as all
   HOTPLUG references.  From Greg KH

6) RDS protocol uses wrong interfaces to access scatter-gather elements,
   causing a regression.  From Mike Marciniszyn.

7) Fix build error in cpts driver, from Richard Cochran.

8) Fix arithmetic in packet scheduler, from Stefan Hasko.

9) Similarly, fix association during calculation of random backoff in
   batman-adv.  From Akinobu Mita.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (21 commits)
  ipv6/ip6_gre: set transport header correctly
  ipv4/ip_gre: set transport header correctly to gre header
  IB/rds: suppress incompatible protocol when version is known
  IB/rds: Correct ib_api use with gs_dma_address/sg_dma_len
  net/vxlan: Use the underlying device index when joining/leaving multicast groups
  tcp: should drop incoming frames without ACK flag set
  netprio_cgroup: define sk_cgrp_prioidx only if NETPRIO_CGROUP is enabled
  cpts: fix a run time warn_on.
  cpts: fix build error by removing useless code.
  batman-adv: fix random jitter calculation
  arp: fix a regression in arp_solicit()
  net: sched: integer overflow fix
  CONFIG_HOTPLUG removal from networking core
  Drivers: network: more __dev* removal
  bridge: call br_netpoll_disable in br_add_if
  ipv4: arp: fix a lockdep splat in arp_solicit()
  tuntap: dont use a private kmem_cache
  net: devnet_rename_seq should be a seqcount
  ip_gre: fix possible use after free
  ip_gre: make ipgre_tunnel_xmit() not parse network header as IP unconditionally
