From 9f455bcb34fcab31b0eb8eec5702105c8d4bde18 Mon Sep 17 00:00:00 2001 From: "oliver@schinagl.nl" Date: Fri, 25 Nov 2016 16:30:20 +0100 Subject: net: cosmetic: Make the MAC address string less magical In u-boot printf has been extended with the %pM formatter to allow printing of MAC addresses. However buffers that want to store a MAC address cannot safely get the size. Add a define for this case so the string of a MAC address can be reliably obtained.
