From 16eecd9be4b05e3216b8b12707aa6f51fb197903 Mon Sep 17 00:00:00 2001 From: Anish Bhatt Date: Mon, 28 Jul 2014 20:57:07 -0700 Subject: dcbnl : Fix misleading dcb_app->priority explanation Current explanation of dcb_app->priority is wrong. It says priority is expected to be a 3-bit unsigned integer which is only true when working with DCBx-IEEE. Use of dcb_app->priority by DCBx-CEE expects it to be 802.1p user priority bitmap. Updated accordingly This affects the cxgb4 driver, but I will post those changes as part of a larger changeset shortly.
