Hi Noa,
Did not review the patchset yet, but it would be good to at least
include some documentation around use cases, and maybe an example to be
used for testing?
Cheers,
Eelco

Introduce dpdkvdpa netdev allowing HW offloads over VirtIO network
devices.
dpdkvdpa ports can be added to netdev bridges with the following
command:
ovs-vsctl add-port br0 vdpa0 -- set Interface vdpa0 type=dpdkvdpa
options:vdpa-socket-path=<sock path>
options:vdpa-accelerator-devargs=<VF pci id>
options:dpdk-devargs=<vdpa pci id>,representor=[id]
vDPA netdev is designed to support both SW and HW acceleration.
SRIOV capable NICs can use the SW acceleration which relays packets
between VF and virtIO ports.
HW mode will configure vDPA capable NICs.
Patch 1 provides the vdpa functionality as a pre-step without a
functional
change.
Patch 2 introduces the dpdkvdpa vport.
