[vortex-bug] 3C905TX doesn't see 10Mbps Net till unplugged/replugged

[Bill Newcomb]

Hello to all and kudos in particular to Mr. Becker for the drivers.  

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.  

Any help would be gratefully appreciated.

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