The GbE support based on the patch for generic 'mii-tool', see
 http://ftp.debian.org/debian/pool/main/n/net-tools/net-tools_1.60-24.2.diff.gz

We need to note Jean-Christophe PLAGNIOL-VILLARD for his
initial GbE support patch:
 http://lists.infradead.org/pipermail/barebox/2013-February/012634.html

Generic 'mii-tool' GbE support patch has some disadvantages:
1. 1000baseT-HD is prefered to 1000baseT-FD;
2. show GbE-features for 10/100 only phys (e.g. Level One LXT971).
This patch fixes this disadvantages.
