fxp watchdog timeout patch

[Mike Silbersack]

Sorry for the delay, here's the patch which should properly implement
watchdog timeout handling in the fxp driver.  If you're one of the people
seeing the false watchdog timeout messages, please give this a whirl and
tell me how it worked.

Thanks,

Mike "Silby" Silbersack
