[PATCH] pcnet32: AT2700/2701 and Bugzilla 2699 & 4551

Browse Source 
This patch is a better fix for Allied Telesyn 2700/2701 FX boards than
the change made in early January this year.  It allows the user to
select the speed/duplex via module_param, but if no selection is made,
forces the speed to 100 FD.  It fixes both Bugzilla bugs 2669 and 4551.
Tested ia32 and ppc64 by myself, and by the originator of bug 2669.
