Most modern cards nowadays can autosense which media port is active, but
what you may also want to consider is SPEED. ifconfig is as good a place
as any to specify both speed and media port.
OSF (i.e. DEC Alpha) does the following in rc.config, for example
to also determine speed (for the DEC Tulip ethernet cards):
IFCONFIG_1="22.214.171.124 netmask 255.255.255.0 broadcast 126.96.36.199 speed 10 up"
(speed can either be 10 or 100 for ethernet devices, 4 or 16 for TokenRing)
Although speed for Token is described in the manpage, it took a bit
of playing around to discover that 10 or 100 would also work :-). The
card defaults to 100 if not specified...
2 more cents.
