The following series implements a change to the rport state machine and
applies a locking strategy to that state machine.
1) A callback function is added to the LP for RP events (READY, FAILED, LOGO)
2) GNN_ID and GPN_ID are moved into the RP state machine
3) The RP state machine starts in a work thread
4) A READY state is added to the RP state machine
5) The RP state machine locking has been given a locking strategy
6) RP only has one error/retry handling routine
7) Naming conventions are changed
rp (remote port) = fc_rport pointer
rpp (remote port private) = fc_rport_libfc_priv pointer
I think these patches still need a little cleaning up, but they're mostly good.
I'm curious what everyone thinks about the folowing changes to:
a) the locking policy
b) the event callback mechanism
c) the use of work threads
d) the consolidation of fc_rport_error and fc_rport_retry.
All comments are welcome. If there are no major issues I'll do a little cleanup,
drop the RFC, resubmit and then commit.
