Subject: [PATCH V3 17/21] qlcnic: 83xx CNA inter driver communication mechanism
From: Sony Chacko <sony.chacko@...gic.com>
Inter Driver Communication (IDC) module.
CNA function drivers(ISCSI, FCOE and NIC) which shares the adapter
relies on IDC mechanism for gracefull shut down, restart and
firmware error recovery.
