From cc4ce020935eab2d261b7b8d24a9843b56ad594c Mon Sep 17 00:00:00 2001 From: Somnath Kotur Date: Thu, 21 Oct 2010 07:11:14 -0700 Subject: be2net: Changes to use only priority codes allowed by f/w Changes to use one of the priority codes allowed by CNA f/w for NIC traffic from host. The driver gets the bit map of the priority codes allowed for host traffic through a asynchronous message from the f/w that the driver subscribes to.
