The t21142_timer routine ignores the TULIP_NO_MEDIA_SWITCH option and
happily
switches between interfaces. However I could transfer up to three packets
out of the
10base2 port before this switching happens.
I disabled the switching code with someting like if (!tp->medialock)...
This seems to work
except some hickups.

Another workaround might be to replace this version with a driver 0.76
comming with
erlier kernels (2.0.30??). I use this with an actual 2.0.34 kernel. But
you have to use the
option command to select the correct interface.
