ipcpd: Add IPCP over DIX Ethernet
This adds an IPC Process that uses DIX Ethernet with an Ethertype that is configurable at bootstrap. This allows parallel DIX layers over the same Ethernet network with different Ethertypes (and one LLC layer). It allows jumbo frames in the future, and should avoid the problems we have with some routers not handling LLC traffic very well. The destination endpoint ID is sent as a 16 bit integer, so the maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes when Jumbo frames are used. The implementation is very similar to the Ethernet LLC IPCP, so it is implemented using preprocessor macros in the single source instead of duplicating code.
