From 695a814e18561c52456acf5051fac0ea4b8111da Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 26 Jan 2010 23:08:03 -0500 Subject: [SCSI] lpfc 8.3.8: BugFixes: Discovery relates changes Discovery relates changes: - Separated VPI_REGISTERED state of physical port into VFI_REGISTERED and VPI_REGISTERED state so that driver can unregister physical port VPI independent of VFI. - Add code to unregister, re-init and re-register physical port VPI when physical port NportID change. - Add code to unregister and re-register VPI of a vport when its Nport ID change. - Add code in FDISC completion path to re-start FLOGI discovery when a FDISC complete with LOGIN_REQUIRED reason code. - Fix a memory leak in lpfc_init_vpi_cmpl - Add code to start a timer for vport to retry FDISC when CVL is received by a vport or physical port. If all Nports receive CVLs, then all timers are cancelled and a logical link level discovery will be started after one second. - Flush ELS commands after killing all delayed ELS commands.
