[SCSI] lpfc 8.1.11 : Discovery Fixes
Discovery Fixes: - Prevent starting discovery of a node if discovery is in progress. - Code improvement (reduction) for lpfc_findnode_did(). - Update discovery to send RFF to Fabric on link up - Bypass unique WWN checks for fabric addresses - Add ndlp to plogi list prior to issuing the plogi els command Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
