From d1d5741d8568c268ec234a5b35af4a04498be6d8 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Mon, 9 Jun 2008 16:33:57 -0700 Subject: [PATCH] macb: use random mac if stored address in EEPROM is invalid We should use a random mac address if the EEPROM doesn't contain a valid one. This makes life on Boards with unprogrammed EEPROM devices easier.
