[parisc-linux] Tulip driver fails to advertise 100baseTx media capability

Just got Debian 3.0 (woody) booted on a C240.  When the Tulip driver is
initialized by the kernel, it fails to advertise the 100baseTx media
capability of the DS21143 chip.  I think this is a kernel issue, not a
Debian or Tulip issue.

Setting the PDC/firmware (v. 6.3, latest for the C240) to force the
100/Full duplex rate at boot time doesn't fix the problem, nor does
issuing an "ether=0,0,[11|14],eth0" to the kernel from the PALO kernel
parameters line.

I think the way Tulip is called by the kernel somehow causes only 10baseT
to be advertised.  It's easy enough to correct after the fact with a
simple "mii-tool -A" command, but it would be nicer if the media
advertising was properly set by the kernel at boot time.  See output of
uname, dmesg, and mii-tool below.

A thousand pardons if this is the wrong list for this bug.  I'll re-post
to the debian-hppa or the tulip list if people think those are the proper
places.
