That doesn't look like a proper commit message.
How about something like:
If a port is brought down for an extended period of time, the
fipvlan counter gets exhausted and the driver will fall back to
default VLAN 1002 and call fcoe_ctlr_link_up to log in. However, the
switch will discard the FLOGI attempt because the VLAN is now
different.
Keep track of the number of FLOGI attempts and if a threshold of
QEDF_FLOGI_RETRY_CNT is exceeded, perform a context soft reset.
