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

Conflicts: drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c net/ipv4/tcp_metrics.c

Overlapping changes between the "don't create two tcp metrics objects with the same key" race fix in net and the addition of the destination address in the lookup key in net-next.

Minor overlapping changes in bnx2x driver.
