[Qemu-devel] [PATCH 00/18] Add support for RDMA MAD |

Hi all.
This is a major enhancement to the pvrdma device to allow it to work with
state of the art applications such as MPI.
As described in patch #5, MAD packets are management packets that are used
for many purposes including but not limited to communication layer above IB
verbs API.
Patch 1 exposes new external executable (under contrib) that aims to
address a specific limitation in the RDMA usrespace MAD stack.
This patch-set mainly present MAD enhancement but during the work on it i
came across some bugs and enhancement needed to be implemented before doing
any MAD coding. This is the role of patches 2 to 4, 7 to 9 and 15 to 17.
Patches 6 and 18 are cosmetic changes while not relevant to this patchset
still introduce with it since (at least for 6) hard to decouple.
Patches 12 to 15 couple pvrdma device with vmxnet3 device as this is the
configuration enforced by pvrdma driver in guest - a vmxnet3 device in
function 0 and pvrdma device in function 1 in the same PCI slot. Patch 12
moves needed code from vmxnet3 device to a new header file that can be used
by pvrdma code while Patches 13 to 15 use of it.
Along with this patch-set there is a parallel patch posted to libvirt to
apply the change needed there as part of the process implemented in patches
10 and 11. This change is needed so that guest would be able to configure
any IP to the Ethernet function of the pvrdma device.

Thanks,
