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..
