Last activity:
	I had just reconfigured the tulip/tg3.
And then started a "DISTCC" run from gsyprf11 with ion's tg3 card
listed as the only other in DISTCC_HOSTS. gsyprf11 and ion are
both connected to the same GigE switch and thus can talk full duplex
at "link rate". gsyprf11 survived and is running
