Subject: linux-next: manual merge of the net tree with the scsi tree

Hi David,

Today's linux-next merge of the net tree got a conflict in
drivers/scsi/fcoe/fcoe.c between commit
1047f22108bd9bfedefd3ff014cb56691dfbaa3f ("[SCSI] fcoe: removes
fcoe_watchdog") from the scsi tree and commit
ab6b85c1d7a1bf6c2b27fb542a7b2404e45b7e24 ("fcoe: consolidates netdev
related config and cleanup for spma mode") from the net tree.

Just overlapping additions.  I fixed it up (see below) and can carry the
fix as necessary.
