hw/rdma: Add support for MAD packets
MAD (Management Datagram) packets are widely used by various modules
both in kernel and in user space for example the rdma_* API which is
used to create and maintain "connection" layer on top of RDMA uses
several types of MAD packets.
For more information please refer to chapter 13.4 in Volume 1
Architecture Specification, Release 1.1 available here:
https://www.infinibandta.org/ibta-specifications-download/
To support MAD packets the device uses an external utility
(contrib/rdmacm-mux) to relay packets from and to the guest driver.
