From 13e5e473699b92f171205e0f5c57c9ebe7922492 Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Sun, 3 Sep 2017 11:35:46 -0700 Subject: [PATCH] ar71xx: Add GRO support to ag71xx On a TL-WN710N, this patch increases iperf performance from ~92.5 to ~93.5 mbps. Keep in mind the WN710N is a 100mbps device. I expect greater numbers from gigabit devices.
