[ofa-general] [PATCH 04/13] QLogic VNIC: Implementation of Control path of communication protocol
Ramachandra K

Wed Apr 30 10:17:54 PDT 2008
From: Poornima Kamath <poornima.kamath at qlogic.com>
This patch adds the files that define the control packet formats
and implements various control messages that are exchanged as part
of the communication protocol with the EVIC/VEx.
