The MTU was not correctly set for the eth-llc ipcp. This also fixes a
missing definition of ETH_MAX_MTU, which was introduced in kernel v4.10.

The eth-dix IPCP was using a hardcoded MTU of 1500 bytes, but could
support higher MTUs. Now jumbo frames are supported.

The truncate was setting the length to the frame length, instead of
the actual payload length to be delivered to the N+1.

An ethertype check was missing for the DIX ethernet IPCP, causing
crashes if there is other traffic on the network.

This writes into the Ethernet device directly from the rdrbuff to
avoid a copy on the write side in the Ethernet IPCPs. This does not
work for the netmap device.

This reads from the Ethernet device directly into the rdrbuff to avoid
a copy on the read side in the Ethernet IPCPs. This does not work for
the netmap device.

This adds a function that locks a thread to a random core. This
greatly improves performance on multi-cpu systems. There is no
portable way to do this, this only implements it for GNU/Linux.

The packets were being sent and read into a buffer that had the
payload length instead of the frame length.

This will check if the Ethertype value is a valid Ethertype in the irm
tool and the eth-dix IPCPd.

Some NICs added padding to the Ethernet II frames causing bad frame
lengths and GPB unpack fails. This adds a 2-byte length field to the
DIX frame to circumvent this.

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.
