From 3ccd4c6167d3b39d52631767ebbf8b5677c5855d Mon Sep 17 00:00:00 2001 From: Oliver Hartkopp Date: Tue, 12 Jan 2010 02:00:46 -0800 Subject: can: Unify droping of invalid tx skbs and netdev stats To prevent the CAN drivers to operate on invalid socketbuffers the skbs are now checked and silently dropped at the xmit-function consistently. Also the netdev stats are consistently using the CAN data length code (dlc) for [rx|tx]_bytes now. Signed-off-by: Oliver Hartkopp Acked-by: Wolfgang Grandegger Signed-off-by: David S.
