IB/mlx4: Add support for IBoE
Add support for IBoE to mlx4_ib. The bulk of the code is handling the new address vector fields; mlx4 needs the MAC address of a remote node to include it in a WQE (for datagrams) or in the QP context (for connected QPs). Address resolution is done by assuming all unicast GIDs are either link-local IPv6 addresses. Multicast group attach/detach needs to update the NIC's multicast filters; but since attaching a QP to a multicast group can be done before the QP is bound to a port, for IBoE we need to keep track of all multicast groups that a QP is attached too before it transitions from INIT to RTR (since it does not have a port in the INIT state).
