OK, we use MANUF in identification... so where is the problem? ;)

My testing patch for b43 "subscribes" for Broadcom's cores only:
static const struct bcma_device_id b43_bcma_tbl[] = {
	BCMA_CORE(BCMA_MANUF_BCM, BCMA_CORE_80211, 0x17, BCMA_ANY_CLASS),
	BCMA_CORE(BCMA_MANUF_BCM, BCMA_CORE_80211, 0x18, BCMA_ANY_CLASS),
	BCMA_CORETABLE_END
};
