From b9650557f3d58924e3be040df0ff7a3dae19ad83 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 14 Apr 2015 12:07:59 +0200 Subject: [PATCH] bgmac: increase rx ring size from 511 to 512 Limiting it to 511 looks like a failed attempt at leaving one descriptor empty to allow the hardware to stop processing a buffer that has not been prepared yet. However, this doesn't work because this affects the total ring size as well Signed-off-by: Felix Fietkau Signed-off-by: David S.
