From 94108194acb45f6cc488c9ff4e8d561c113f6409 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Mon, 10 Oct 2011 23:43:53 +0200 Subject: can: dev: let can_get_echo_skb() return dlc of CAN frame can_get_echo_skb() is usually called in the TX complete handler. The stats->tx_packets and stats->tx_bytes should be updated there, too. This patch simplifies to figure out the size of the sent CAN frame.
