From 14d1232f490c1c696582909fb3b69e67a8d38a34 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20Miros=C5=82aw?= Date: Tue, 22 Feb 2011 16:52:28 +0000 Subject: [PATCH] net: avoid initial "Features changed" message MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Avoid "Features changed" message and ndo_set_features call on device registration caused by automatic enabling of GSO and GRO. Driver should have enabled hardware offloads it set in features, so the ndo_set_features() is not needed at registration time. Signed-off-by: Michał Mirosław Signed-off-by: David S.
