From 8390f81482e3bbf756dce3a5121f164140fd0412 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 3 Sep 2013 15:13:43 +0300 Subject: [PATCH] atm: nicstar: re-use native mac_pton() helper There is a nice helper to parse MAC. Let's use it and remove custom implementation. Signed-off-by: Andy Shevchenko Signed-off-by: David S.
