PORT UPDATE asynchronous event is generated on the host that issues PLOGI ELS (in the case of higher WWPN). In that case, the event shouldn't be handled as it sets unwanted DPC flags (i.e. LOOP_RESYNC_NEEDED) that trigger link flap. Ignore the event if the host has higher WWPN, but handle otherwise.
