From c26f40daf4e32f970b8337a88b65a8d00332ae6f Mon Sep 17 00:00:00 2001 From: Raanan Avargil Date: Tue, 22 Dec 2015 15:35:03 +0200 Subject: [PATCH] e1000e: Set HW FIFO minimum pointer gap for non-gig speeds Based on feedback from HW team, the configured value of the internal PHY HW FIFO pointer gap was incorrect for non-gig speeds. This patch provides the correct configuration.
