From 37ea0558b87abb151245bc750070a4dcda490aca Mon Sep 17 00:00:00 2001 From: Krishna Gudipati Date: Wed, 20 Jul 2011 17:02:11 -0700 Subject: [SCSI] bfa: Added support to collect and reset fcport stats - Added support to collect and reset fcport stats. - Modified design to allow multiple requests for fcport stats. - fcport will remember the stats request in its stats_pending queue and service each of the queued requests after receiving a firmware response for the prior request.
