I talked to Jason about "ifconfig" flags.

What I really want to do is
	ifconfig lmch0 1.2.3.4 1.2.3.5 netmask 0xfffffffe linktype chdlc

Right now, the HSSI, T3, and soon to be T1 driver I'm doing for Lan
Media relies on link[012] but the T1 card has a clock generator, so
will need a userland control program.

BTW, there is a SDL T1 driver in the tree already...
