DM9000: Add support for DM9000A and DM9000B chips
Add support for both the DM9000A and DM9000B versions of the DM9000 networking chip. This includes adding support for the Link-Change IRQ which is used instead of polling the PHY every 2 seconds. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
