From bf08611bcc461d83199a8449930b176823017f58 Mon Sep 17 00:00:00 2001 From: James Smart Date: Sun, 21 Aug 2011 21:48:13 -0400 Subject: [SCSI] lpfc 8.3.26: Fix issues pertaining to SCSI/FC protocol. Fix issues pertaining to SCSI/FC protocol. - Allow frames destined to 0xFFFFFE to be processed by the driver by matching that DID with the physical port. - Call lpfc_sli_issue_iocb with context1 set to ndlp - In echo command accept function, adjust memcpy to limit memcpy to 1K - Set LPFC_SLI3_BG_ENABLED properly upon completion. - Skip the INIT_VFI call in lpfc_register_fcf if the FCF is already registered and go immediately to initial flogi. - use "status" variable instead of "ret" variable to hold the return of the fc_block_scsi_eh.
