Added option to disable Ethernet auto media detection (Auto-MDIX)

Disabling this works around interoperability issues with some Ethernet switches (that also auto-detect cross-over cables)
To disable: echo 0>/var/config/automdix; reboot
To enable (default): echo 1>/var/config/automdix; reboot

This was implemented in firmware version (1.04G). For update instructions please go to this link:
