libfc, libfcoe and fcoe updates for scsi-misc

The following series implements multiple bug fixes, FCoE VN2VN mode and a VLAN ID patch revert.

VN2VN is a point-to-multipoint FCoE mode. It allows direct connections from the initiator to VN2VN capable FCoE targets.

The VLAN ID revert removes the VLAN ID from the generated WWPN. Adding the VLAN ID to the WWPN is not typical and can cause zoning issues in a variety of scenarios. Note that this change will cause a one time rezone for the new WWPN.

Please apply these patches to scsi-misc.
