From cdd0db058d64f2619b08e7d098ee0014aa0a5bc1 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 28 May 2009 00:00:41 +0000 Subject: net: dont update dev->trans_start Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round) 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.
