From 8093315a91340bca52549044975d8c7f673b28a1 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sat, 29 Dec 2012 16:26:10 +0000 Subject: [PATCH] veth: extend device features MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit veth is lacking most modern facilities, like SG, checksums, TSO. It makes sense to extend dev->features to get them, or GRO aggregation is defeated by a forced segmentation.
