SVN rev 186137 on 2008-12-15 21:36:14Z by marius
MFC: 185750
- According to the corresponding Linux, NetBSD and OpenSolaris
drivers, there should be a 1us delay after every write when
bit-banging the MII. Also insert barriers in order to ensure
the intended ordering. These changes hopefully will solve the
bus wedging occasionally experienced with DM9102A since r182461.
- Deobfuscate dc_mii_readreg() a bit.
