scsi: qedf: Stop sending fipvlan request on unload
- On some setups fipvlan can be retried for long duration and the connection to switch was not there so it was not getting any reply. - During unload this thread was hanging. Problem Resolution: Check if unload is in progress, then quit from fipvlan thread. Signed-off-by: Saurav Kashyap <skashyap@marvell.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
