[SCSI] bnx2fc: Handle LOGO flooding from the target
Host drops sessions when flood of unsolicited LOGOs are received from the target. Because of unsufficient PLOGI retries, upon exceeding the retry count of 3, the target sessions are dropped. Increased the retry count to 255 to allow sufficient retries in this scenario. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
