Public bug reported:
[Impact]
Although focal kernel supports non FDB domains, rdma-core support is missing.
we need the below rdma-core patches to add this support
[Test Case]
install latest DPDK from github
$ git clone git://dpdk.org/dpdk
$ cd <dpdk download folder>
$ mason build
$ ninja -C build
- Run testpmd
/download/dpdk/build-meson/app/dpdk-testpmd -n 4 -a
