2018-12-22hw/pvrdma: Add support to allow guest to configure GID tableYuval Shaia11-163/+462
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.

2018-12-22hw/rdma: Add support for MAD packetsYuval Shaia5-10/+260
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.

2018-12-22hw/rdma: Add ability to force notification without re-armYuval Shaia3-5/+21
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.

PVRDMA is the QEMU implementation of VMware's paravirtualized RDMA device. It works with its Linux Kernel driver AS IS, no need for any special guest modifications. While it complies with the VMware device, it can also communicate with bare metal RDMA-enabled machines and does not require an RDMA HCA in the host, it can work with Soft-RoCE (rxe). It does not require the whole guest RAM to be pinned allowing memory over-commit and, even if not implemented yet, migration support will be possible with some HW assistance. Implementation is divided into 2 components, rdma general and pvRDMA specific functions and structures. The second PVRDMA sub-module - interaction with PCI layer. - Device configuration and setup (MSIX, BARs etc). - Setup of DSR (Device Shared Resources) - Setup of device ring. - Device management.
