From f9c3fe2f43343be7972226c2e736e7a68e383dc1 Mon Sep 17 00:00:00 2001 From: "Chopra, Manish" Date: Thu, 11 May 2017 07:12:47 -0700 Subject: [PATCH] qlcnic: Fix link configuration with autoneg disabled Currently driver returns error on speed configurations for 83xx adapter's non XGBE ports, due to this link doesn't come up on the ports using 1000Base-T as a connector with autoneg disabled. This patch fixes this with initializing appropriate port type based on queried module/connector types from hardware before any speed/autoneg configuration.
