[PATCH] tulip, kernel 2.4.26-rc1

[Timothy I Mattox <tmattox@xxxxxxxxxxxx>]

Here is a patch for the tulip driver found in kernel 2.4.26-rc1
This adds MII functionality to the ADMtek Comet flavor of the tulip,
specifically, the ability to detect and report the link status with MII.

I've tested on several Linksys LNE100TX v4.1 PCI cards, as well as on
an HP Pavilion N5475 laptop with a built-in NIC that is detected as
this same model of chip.

This patch was modeled after Donald Becker's tulip.c:v0.98 1/8/2004, but
the specific bits from his driver have been there for about two years.

Please apply to 2.4 mainline.  If this is accepted, I will convert & 
test it for the 2.6 kernel series as well.
