From 4bce240f2747ea9610ef8aa7b425f3bae5dd07dd Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 5 Apr 2016 14:08:56 -0400 Subject: [PATCH] bnxt_en: Improve flow control autoneg with Firmware 1.2.1 interface. Orabug: 23221795 Make use of the new AUTONEG_PAUSE bit in the new interface to better control autoneg flow control settings, independent of RX and TX advertisement settings.
