From 03f3d8d3b39cf85c0ce7ca903b436701e8aa610b Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 11 Feb 2009 19:09:54 -0500 Subject: lan91c96/smc91111/smc911x: get mac address from environment The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Also, do not bother checking the EEPROM if the env is setup. This simplifies the code greatly.
