From 5b548140225c6bbbbd560551dd1048b2c0ce58be Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Fri, 12 Jun 2009 06:22:29 +0000 Subject: net: use symbolic values for ndo_start_xmit() return codes Convert magic values 1 and -1 to NETDEV_TX_BUSY and NETDEV_TX_LOCKED respectively. 0 (NETDEV_TX_OK) is not changed to keep the noise down, except in very few cases where its in direct proximity to one of the other values.
