From a5250a36954c6658e28cc2e7e07e314e0c79e8bb Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 21 Jan 2008 00:24:13 -0800 Subject: [PATCH] [ETHER]: Bring back MAC_FMT The print_mac function is not very suitable for debugging printks in performance critical paths since without ifdefs it will always get called. MAC_FMT can be used with pr_debug without any overhead when debugging is disabled. Signed-off-by: Patrick McHardy Signed-off-by: David S.
