The FC standard has defined a new Fabric Performance Impact Notification (FPIN) ELS that can be sent from the fabric to an endpoint to communicate fabric integrity information. The FPIN may communicate congestion detection, link integrity issues, or other similar conditions. This patch set adds minimal support for the new FPIN ELS which is still being worked in T11. The base ELS format is defined and scsi_transport_fc is updated to allow an lldd to pass it an FPIN, which the transport will post as an fc event with the FPIN payload. In the future, it may be interesting to parse the payload and set attributes on different fc ports. The last patch updates the lpfc driver to post a received FPIN. These patches were cut from the 5.2/scsi-queue branch.
