Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: drivers/net/ethernet/broadcom/tg3.c Conflicts in the statistics regression bug fix from 'net', but happily Matt Carlson originally posted the fix against 'net-next' so I used that to resolve this. Signed-off-by: David S. Miller <davem@davemloft.net>
