The following commit has been merged in the master branch: commit 58717686cf7c7f5a70b3a8907ade8a3ce74306b1 Merge: cff63a52924c6a78fa525c67d81480c85736ff3c 79f632c71bea0d0864d84d6a4ce78da5a9430f5b Author: David S. Miller davem@davemloft.net Date: Tue Apr 30 03:50:54 2013 -0400

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

Conflicts: drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c drivers/net/ethernet/emulex/benet/be.h include/net/tcp.h net/mac802154/mac802154.h

Most conflicts were minor overlapping stuff.

The be2net driver brought in some fixes that added __vlan_put_tag calls, which in net-next take an additional argument.
