Leaves only 1 warning still reproduceable : 
(LIBFCOE && TCM_QLA2XXX) selects LIBFC which has unmet direct dependencies (SCSI_LOWLEVEL && SCSI && SCSI_FC_ATTRS),
 so maybe that needs a fix too ? All the other fcoe/scsi menu entries behave 
as expected.

From: Randy Dunlap <rdunlap@...radead.org>

Don't enable NETDEVICES when NET is not enabled. That causes
build warnings and errors.
