interace cleanups, some new common functions. The major impact that
will be noticeable right away is that if you boot with not Fibre connected
to the FC cards, you no longer hang indefinitely.
Correctly account for F-port vs. F-port (no FLOGI_ACC) topologies.
Make sure we get a port database entry for the fabric name server.
Preserve fabric logins if the device didn't change across fabric
or port database changes, or the device has already logged into
us (e.g., for target/initiator dual role devices like Veritas
SANbox). Propagate class 3 service parameter changes where devices
can change roles.
Fix all occurrences of setting a sendmarker so that setting it
for one bus on dual bus cards doesn't wipe a pending sendmarker
for other busses on the same card :-;.
Comments added and clarifications made in some of the target mode code.
