/*
 . Function: l91_update_multi(struct netif *netif)
 . Purpose:
 . This sets the internal hardware table to filter out unwanted multicast
 . packets before they take up memory.
 .
 . The SMC chip uses a hash table where the high 6 bits of the CRC of
 . address are the offset into the table. If that bit is 1, then the
 . multicast packet is accepted. Otherwise, it's dropped silently.
 .
 . To use the 6 bits as an offset into the table, the high 3 bits are the
 . number of the 8 bit register, while the low 3 bits are the bit within
 . that register.
 .
 . This routine is based very heavily on the one provided by Peter Cammaert.
