From 3958ffcd85060967a9c70bb92b21741073578d66 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Wed, 11 Oct 2017 14:52:24 -0500 Subject: [PATCH] net: qcom/emac: remove unused address arrays The EMAC is capable of multiple TX and RX rings, but the driver only supports one ring for each. One function had some left-over unused code that supports multiple rings, but all it did was make the code harder to read. Signed-off-by: Timur Tabi Signed-off-by: David S.
