From 1ae5dc342ac78d7a42965fd1f323815f6f5ef2c1 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 10 May 2010 05:01:31 -0700 Subject: net: trans_start cleanups Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler. Exceptions are NETIF_F_LLTX drivers Signed-off-by: Eric Dumazet Signed-off-by: David S.
