2 MHz Mode
2 MHz mode increases the rate at which data is transferred on the twinax line.
Normally, data is transferred at 1 Mbps, but the 2 MHz mode doubles the line
speed, allowing transfers to occur at 2 Mbps.
NOTE
All stations on the line must be 2 MHz capable in order for this function
to work. If there is even one station at the lower speed, all stations will
drop down to the lower speed.
