Yuval Shaia bf4414515b hw/rdma: Free all receive buffers when QP is destroyed
When QP is destroyed the backend QP is destroyed as well. This ensures
we clean all received buffer we posted to it.
However, a contexts of these buffers are still remain in the device.
Fix it by maintaining a list of buffer's context and free them when QP
is destroyed.

Yuval Shaia 4d71b38ae8 hw/rdma: Switch to generic error reporting way
Utilize error_report for all pr_err calls and some pr_dbg that are
considered as errors.
For the remaining pr_dbg calls, the important ones were replaced by
trace points while other deleted.
Some of the functions got renamed to include prefix "rdma/pvrdma"
in the function name.

Yuval Shaia 028c3f93d6 hw/rdma: Initialize node_guid from vmxnet3 mac address
node_guid should be set once device is load.
Make node_guid be GID format (32 bit) of PCI function 0 vmxnet3 device's
MAC.

A new function was added to do the conversion.
So for example the MAC 56:b6:44:e9:62:dc will be converted to GID
54b6:44ff:fee9:62dc.

Yuval Shaia 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.
