From 4cd5773a2ae6facdde3f563087a4cc50f00d9530 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 4 Jun 2013 19:46:26 +0300 Subject: net: core: move mac_pton() to lib/net_utils.c Since we have at least one user of this function outside of CONFIG_NET scope, we have to provide this function independently. The proposed solution is to move it under lib/net_utils.c with corresponding configuration variable and select wherever it is needed.
