From 991b6722fb727b6e2a98e7e8b57176ac68626110 Mon Sep 17 00:00:00 2001
From: Hauke Mehrtens <hauke@hauke-m.de>
Date: Thu, 3 Oct 2013 20:41:29 +0200
Subject: [PATCH 2/5] b44: rename B44_PHY_ADDR_NO_PHY to
B44_PHY_ADDR_NO_LOCAL_PHY
The PHY address 30 means there is no local PHY, but there could be an
external PHY like a switch connected via MII. This is the case on most
embedded home routers where this driver is used.
