14c74f7207 hw/rdma: Remove unneeded code that handles more that one port
Device supports only one port, let's remove a dead code that handles
more than one port.

2b05705dc8 hw/pvrdma: Add support to allow guest to configure GID table
The control over the RDMA device's GID table is done by updating the
device's Ethernet function addresses.
Usually the first GID entry is determined by the MAC address, the second
by the first IPv6 address and the third by the IPv4 address. Other
entries can be added by adding more IP addresses. The opposite is the
same, i.e. whenever an address is removed, the corresponding GID entry
is removed.

The process is done by the network and RDMA stacks. Whenever an address
is added the ib_core driver is notified and calls the device driver
add_gid function which in turn update the device.

To support this in pvrdma device we need to hook into the create_bind
and destroy_bind HW commands triggered by pvrdma driver in guest.
Whenever a change is made to the pvrdma port's GID table a special QMP
message is sent to be processed by libvirt to update the address of the
backend Ethernet device.

0efc9511aa rdma: fix up include directives
Our rule right now is to use <> for external headers only.
RDMA code violates that, fix it up.

ef6d4ccdc9 hw/rdma: Implementation of generic rdma device layers
This layer is composed of two sub-modules, backend and resource manager.
Backend sub-module is responsible for all the interaction with IB layers
such as ibverbs and umad (external libraries).
Resource manager is a collection of functions and structures to manage
RDMA resources such as QPs, CQs and MRs.
