Changes to the Ariadne ethernet driver

[Bernd Ernesti <netbsd%arresum.inka.de@localhost>]

Hi,

I moved ealier today the Ariadne support from the special if_ae.c driver
to the more generic if_le.c driver.
Charles M. Hannum send me a diff to integrate the Ariadne to the if_le.c
driver about 16 months ago, but i had some problems with it at that time,
so i put it on hold.
Now, I thought about to use the new ifmedia changes in the if_ae.c driver,
but i hate it to integrate ever MI lance change to if_ae.c, so I started
again with one lance driver for the A2065, Ameristar and Ariadne.
I got a extra A2065 so I could test it with the Ariadne in one computer.
It works now, the A2065 has a speed of 610KB/s and the Ariadne 630KB/s.

You need to rerun config after you sup or you get an error and you need to
rename your /etc/hostname.aeX to /etc/hostname.leX (where X is normally 0).
And you have to change any link0 or link1 keywords to the new ifmedia syntax,
you find more in the new manpage for le and the ifconfig manpage.
