Description
HT3 Hash Table 3
When the appropriate bit is set, if the packet received with DA matches the CRC, the
hashing function is received without being filtered.
When the appropriate bit is cleared, the packet will drop.
Note: When the receive all (RXAE) or receive multicast (RXME) bit is set in the RXCR1, all
multicast addresses are received regardless of the multicast table value.
