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

Conflicts:
	drivers/net/ethernet/emulex/benet/be.h
	drivers/net/netconsole.c
	net/bridge/br_private.h

Three mostly trivial conflicts.

The net/bridge/br_private.h conflict was a function signature (argument
addition) change overlapping with the extern removals from Joe Perches.

In drivers/net/netconsole.c we had one change adjusting a printk message
whilst another changed "printk(KERN_INFO" into "pr_info(".

Lastly, the emulex change was a new inline function addition overlapping
with Joe Perches's extern removals.

Datagram Congestion Control Protocol (DCCP) is an unreliable, connection
oriented protocol designed to solve issues present in UDP and TCP, particularly
for real-time and multimedia (streaming) traffic.
It divides into a base protocol (RFC 4340) and plugable congestion control
modules called CCIDs. Like plugable TCP congestion control, at least one CCID
It divides into a base protocol (RFC 4340) and pluggable congestion control
modules called CCIDs. Like pluggable TCP congestion control, at least one CCID
needs to be enabled in order for the protocol to function properly. In the Linux
implementation, this is the TCP-like CCID2 (RFC 4341). Additional CCIDs, such as
the TCP-friendly CCID3 (RFC 4342), are optional.
