New Revision: 211792
URL: http://svn.freebsd.org/changeset/base/211792
Log:
Prodded by Yongari, add support for Holtek HT80232. Add the device
ID, plus the ability to force '16-bit mode' which really means NE-2000
mode. Other open source drivers suggest that the Holtek misbehaves if
you allow the 8-bit probe. Also, all of the PCI chips emulate
NE-2000ish cards, so always force 16-bit mode for memory transfers.
