[vortex] 3C905TX doesn't see 10Mbps hub till unplugged/replugged

[Bill Newcomb]

(forgive me if I am a megabozo, and this message doesn't belong on
this list, but rather only on vortex-bug, where I posted it a week
ago.  Maybe all the vortex-bug readers are on summer vacation :-)

I have a 3C905TX in my linux box which doesn't seem to see that it's
plugged in to the cheapie 10BaseT hub when it boots up.  If I then
disconnect the Ethernet cable and reconnect it, however, lights go on
at the card and the hub, and all is well.  I haven't tried it with any
other hub equipment, so I don't know if it's the hub, or a config
mistake on my part.  I scrounged around in the archives a bit, and
didn't see this exact problem, so I assume it's not a flat-out bug in
the driver.  I originally had 0.99H(?), and upgraded to 0.99Q, but
that didn't seem to change anything.  I'd rather not "hard-wire" the
transceiver setting if I don't have to, as it would be nice to not
have to change something else when I rove around to other networks. 

Any help would be gratefully appreciated.

Here's the output of mii-diag, before and after I do the
unplug/replug.
