From 4a55530f38e4eeee3afb06093e81309138fe8360 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 7 Mar 2011 21:59:26 +0000 Subject: [PATCH] net: sh_eth: modify the definitions of register The previous code cannot handle the ETHER and GETHER both as same time because the definitions of register was hardcoded.
