Commit a9277e77 "[SCSI] scsi_transport_fc: Getting FC Port Speed in sync with FC-GS" changed the semantics of FC_PORTSPEED defines to FDMI port attributes of FC-HBA/SM-HBA which is different from the previous bit reversed Report Port Speed Capabilities (RPSC) ELS of FC-GS/FC-LS. Zfcp showed "10 Gbit" instead of "4 Gbit" for supported_speeds. It now uses explicit bit conversion as the other LLDs already do, in order to be independent of the kernel bit semantics.

gcc 4.8 warns because the memset only clears sizeof(char *) bytes, not the whole buffer. Use the correct buffer size and clear the whole sense buffer. /backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c: In function 'bnx2fc_parse_fcp_rsp': /backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c:1810:41: warning: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to provide an explicit length?

It does not make sense to translate ref tags with unexpected values. Instead we simply ignore them and let the upper layers catch the problem. Ref tags that contain the expected value are still remapped. Signed-off-by:

This fixes an issues seen where a Fabric RSCN event was received while the link was down, which resulted in repeated attempts to log back into the fabric, which then failed, resulting in the ibmvfc driver taking the host offline. Fix this by delaying taking any action regarding the fabric RSCN until the link comes back up. Signed-off-by:

If an abort request times out to the virtual fibre channel adapter, the ibmvfc driver will kick off a reset of the adapter. This patch ensures we wait for the both the abort request and the request being aborted to be completed prior to exiting the eh_abort handler. This fixes a bug where the ibmvfc driver was erroneously returning success to the eh_abort handler then later sending back a response to the same command. Signed-off-by:

- Changes to avoid discovering NPIV port as remote port by the other NPIV ports created on same physical port when all the NPIV ports are part of the same zone in a fabric. - Provided mechanism to support maximum number of target ports for a given initiator port (physical port + NPIV ports) irrespective of the way in which the initiator and target ports are zoned in the fabric. - Introduced module_parameter max_rport_logins to restrict number of remote ports discovery which includes target and initiator remote ports.

- Added few missing endian swap changes to support BFA on PowerPC. - Added PCIE AER support to BFA: a) Implemented the PCI error handler entry points. b) Made changes to FCS state machine to handle STOP event from the PCI error detected entry point. c) Made changes to the IO Controller state machine to handle SUSPEND event from the PCI error detected entry point. d) Made changes to restart the BFA operations on a slot_reset completion.

- Introduced rport qualifier structure and modified design to export remote ports with valid pid or valid pwwn to the user space. - Introduced old_pid field in the rport structure and made changes to prevent re-creating a new remote port for an already existing rport that is transitioning to a delete state. (Happens if we receive a RSCN on the existing remote port that is getting deleted). Signed-off-by:
