Probably my SVEC is one of the "two-in-one" cards :-) usually 'two-in-one' cards use the same controller (e.g. NE/WD/SMC), not a totally different one. Some do emulate different cards (common with video cards or SCSI controller) but the additional complexity requires a good payoff in terms of volume (Video cards, where additional performance motivate extensions to the VGA chipset, yet backward compatibility reasons force to emulate VGA/EGA/CGA) or relatively high margins on each card (SCSI controllers, where also often a microcontroller handles the protocol with the host, and emulation is not that expensive). I do not see these two motivations in building a lnc&ed network card.
