Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
The forcedeth changes had a conflict with the conversion over to atomic u64 statistics in net-next. The libertas cfg.c code had a conflict with the bss reference counting fix by John Linville in net-next. Conflicts: drivers/net/ethernet/nvidia/forcedeth.c drivers/net/wireless/libertas/cfg.c
