Hi Joe,

Current implementation only sets "port select" bit for non-1Gb mode. That works fine if GMAC has just exited reset state but we may as well change connection mode in runtime. Then we'll need to reprogram GMAC for that new mode of operation and if previous mode was 10 or 100 Mb and new one is 1 Gb we'll need to reset port mode bit.

Any chance for that one to be applied?
