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.
