* hw/rdma: Protect against concurrent execution of poll_cqYuval Shaia2019-03-161-0/+1
| | | | | | | | | | | | | | The function rdma_poll_cq is called from two contexts - completion handler thread which sense new completion on backend channel and explicitly as result of guest issuing poll_cq command. Add lock to protect against concurrent executions.

* hw/pvrdma: Add support to allow guest to configure GID tableYuval Shaia2018-12-221-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* hw/rdma: Add ability to force notification without re-armYuval Shaia2018-12-221-1/+7
| | | | | | | | | | | | | | | Upon completion of incoming packet the device pushes CQE to driver's RX ring and notify the driver (msix). While for data-path incoming packets the driver needs the ability to control whether it wished to receive interrupts or not, for control-path packets such as incoming MAD the driver needs to be notified anyway, it even do not need to re-arm the notification bit. Enhance the notification field to support this.
