* With more knowledge of the target system, it would be possible to overcome
* these limitations, by using UDP port ranges in the protocol detection.
* It is relatively simple to add this functionality to the templates presented
* below, by adjusting the protocol mask to include some of the bits in the
* UDP ports. For each protocol, the UDP header is identified in the protocolMaskBytes
* initialiser values. To provide a range of 256 destination ports for each protocol,
* simply change the 3rd byte in the UDP header to 0. This will match the upper
* 8 bits of the UDP dest port in classification. The function zl5011xPacketRxSetProtocolFunc
* handles this mutual exclusion and will need to be modified to now allow the
* conflicting protocols to be configured. The switch statement a few lines after
* the function call zl5011xLanRxSetProtocolMatch is used to update protocols that are
* excluded by setting the current protocol. Simply removing all of the IP_UDP protocol
* switch statements will allow the default behaviour and hence allow the protocols to
* interoperate. A similare change is needed to function zl5011xPacketRxDeleteHeader
* if it is required to remove a protocol.
*
* ETHERNET If used, this should always occupy the highest numbered (lowest priority) of any
* protocol match(es) used as it is intended as a catch-all for packets that do not
* match anyother protocol match.
* If matchDestMacAddress is set then only packets destined for a particular MAC
* will match. Otherwise any Ethernet packet will match this protocol.
