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

Conflicts:
	drivers/net/ethernet/emulex/benet/be.h
	drivers/net/usb/qmi_wwan.c
	drivers/net/wireless/brcm80211/brcmfmac/dhd_bus.h
	include/net/netfilter/nf_conntrack_synproxy.h
	include/net/secure_seq.h

The conflicts are of two varieties:

1) Conflicts with Joe Perches's 'extern' removal from header file
   function declarations.  Usually it's an argument signature change
   or a function being added/removed.  The resolutions are trivial.

2) Some overlapping changes in qmi_wwan.c and be.h, one commit adds
   a new value, another changes an existing value.  That sort of
   thing.
