Sorry for long threads.

Ummm...

This gives exactly the same results for my cases (a) and (b) under
2.4.6.  Is this bogus? Note that the internal adapter works properly
only in case (a).

Here I show again "mii-diag -v" for both cases (a) and (b)
under the kernel 2.4.6.

Here I can find "Link status: not established." or "negotiation not

Any ideas?

Thanks.
