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.
