Description Marcus Barrow 2008-11-20 16:02:38 UTC 
QLogic testing is showing that the FCoE adapter is unable to bring up it's link. This is because of an additional initialization step required by the ethernet hardware. In upstream this code would be called thru the scsi_start_scan interface which is not present in rhel 5.

This is a simple patch which explicitly calls the additional initialization routine for the FCoE hardware.

It applies and builds cleanly to 2.6.18-123, and is observed to fix the problem at QLogic.

Kernel panic log during qla2xxx unload

With the latest qla2xx driver v8.02.00.06.05.03-k, I did hit a kernel panic while unloading the driver. This is intermittent.
