82xx: FCC: Fixing a bug causing to FCC port lock-up
The patch fixes FCC port lock-up, which occurs as a result of a bug
during underrun/collision handling. Within the tx_startup() function
in mac-fcc.c, the address of last BD is not calculated correctly.
As a result of wrong calculation of the last BD address, the next
transmitted BD may be set to an area out of the transmit BD ring.
This actually causes to port lock-up and it is not recoverable.
