What is this code I found in bwn?

[Kiernan Hager]

In gnu/dev/bwn/phy_n/if_bwn_phy_n_tables.c, i found this code lurking:

	/* Auto increment broken + caching issue on BCM43224? */
	if (siba_get_chipid(sc->sc_dev) == 43224 &&	siba_get_revid(sc->sc_dev) == 1) {
		BWN_PHY_READ(mac, BWN_NPHY_TABLE_DATALO);
		BWN_PHY_WRITE(mac, BWN_NPHY_TABLE_ADDR, offset + i);
	}

Does this mean that there is some level of support for the BCM43224 in
the bwn driver? Or is it just something for identification?
