[QLogic 5.3 bug] qla2xx/qla84xx - Failure to establish link.
Last modified: 2009-06-20 04:12:49 EDT
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.
