As Christoph mentioned, the firmware images are auto-generated, so I'd
rather hold off on those deltas.  Besides, I'm hoping in the near
future to drop the firmware from the distribution and begin to use the
request_firmware() interface exclusively.

The driver is also going through some significant overhauling with the
fc_remote_port stuffs -- where most internal queueing is stripped from
the driver.

these codes will be dropped from the driver.
