Revision 79aa05a24f01bcb0cfbac3deea4f12d9b4f64ba9 authored by Martin Roth on 15 December 2015, 02:17:53 UTC, committed by David S. Miller on 16 December 2015, 23:32:35 UTC
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.
