Does a netdev_for_each_mc_addr loop entry really
need to verify that the address is multicast?
Couldn't this just be:
netdev_for_each_mc_addr(ha, dev) {
crc = ether_crc(ETH_ALEN, ha->addr);
crc >>= 26;
if (crc & 0x20)
emac_hashhi |= 1 << (crc & 0x1f);
else
emac_hashlo |= 1 << (crc & 0x1f);
}

It could, and I'd be happy to apply a follow-on patch that does
this.
