Name bridgeCalcMMACHash
Description
This variable is used to calculate a hash value based on the address in bridgeMMAC. Writing a
value different than bridgeMMACHashDone to this variable causes the calculation to begin. When
complete, bridgeMMACHashDone will be updated with the value written here and
bridgeMACHashBuf will contain the new hash value. Folding bridgeMACHashBuf resuls into
bridgeHashBuf will then allow receipt of packets from the multicast address specified in
bridgeMMAC.
