[eoib] Add Ethernet over Infiniband (EoIB) driver
EoIB is a fairly simple protocol in which raw Ethernet frames
(excluding the CRC) are encapsulated within Infiniband Unreliable
Datagrams, with a four-byte fixed EoIB header (which conveys no actual
information). The Ethernet broadcast domain is provided by a
multicast group, similar to the IPoIB IPv4 multicast group.
The mapping from Ethernet MAC addresses to Infiniband address vectors
is achieved by snooping incoming traffic and building a peer cache
which can then be used to map a MAC address into a port GID. The
address vector is completed using a path record lookup, as for IPoIB.
Note that this requires every packet to include a GRH.
Add basic support for EoIB devices. This driver is substantially
derived from the IPoIB driver. There is currently no mechanism for
automatically creating EoIB devices.
