fix fxp(4) so that it will reset the link when you change the speed...  This will fix a problem where you boot w/ the default of autoselect, but then set the speed to 100/full, the switch will keep the autoselect/100/full negotiation...  This will continue to work till someone resets the switch or unplugs the cable resulting in the switch failing to autoneg and falling back to 100/half, causing a hard to track down duplex mismatch..
