From 1abbc98a8ac5c6cc016e672e5888b6416ae243f6 Mon Sep 17 00:00:00 2001 From: Toshiaki Makita Date: Fri, 27 Mar 2015 14:31:16 +0900 Subject: [PATCH] igb: Enable TSO for stacked vlan As datasheets for igb (I210, I350, 82576, etc.) say, maclen can be from 14 to 127, which is enough for reasonable number of vlan tags. My netperf test showed I350's TSO works pretty fine with multiple vlans. Signed-off-by: Toshiaki Makita Acked-by: Jeff Kirsher Signed-off-by: David S.
