the 3c450-TX HomeConnect. Like the 3cSOHO100-TX OfficeConnect, this NIC uses the same ASIC as the 3c905B/3c905C but is targeted for a particular market segment (home users). It is somewhat less expensive than the 3c905B/3c905C ($49, according to the 3Com web site), comes with its own custom driver kit and is bundled with various goofy Windows software packages designed to demonstrate the niftyness of home networking (networked game demos, etc...). Changes are: - Add PCI ID to list in if_xlreg.h. - Update xl_devs table in if_xl.c. - Update xl_choose_xcvr() to consider the HomeConnect the same as all the other 10baseT/100baseTX cards.
