[fc] Do not use the command reference number in FCP_CMND IUs
The FCP command reference number is intended to be used for
controlling precise delivery of FCP commands, rather than being an
essentially arbitrary tag field (as with iSCSI and SRP).
Use the Fibre Channel local exchange ID as the tag for FCP commands,
instead of the FCP command reference. The local exchange ID does not
appear within the FCP IU itself, but does appear within the FC frame
header; debug traces can therefore still be correlated with packet
captures.

[fc] Update ELS port IDs when receiving an ELS frame
The port ID assigned by the FLOGI response is implicit in the
destination ID used for the response (which will differ from the
source ID used for the corresponding request).

[fc] Allow FLOGI response to be sent to newly-assigned peer port ID
The response to a received FLOGI should probably be sent to the peer
port ID assigned as a result of the WWPN comparison.
