[SCSI] bfa: kdump fix on 815 and 825 adapters
Root cause: When kernel crashes, On brocade 815/825 adapters, bfa IOC state machine and FW doesn't get a notification and hence are not cleanly shutdown. So registers holding driver/IOC state information are not reset back to valid disabled/parking values. This causes subsequent driver initialization to fail during kdump kernel boot. Fix description: during the initialization of first PCI function, reset corresponding register when unclean shutown is detect by reading chip registers. This will make sure that ioc/fw gets clean re-initialization. Signed-off-by: Vijaya Mohan Guvva <vmohan@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
