Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: Documentation/networking/ip-sysctl.txt drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c Both conflicts were simply overlapping context. A build fix for qlcnic is in here too, simply removing the added devinit annotations which no longer exist. Signed-off-by: David S. Miller <davem@davemloft.net>
