Ben,
I had this working with 19.02 with my patch using dpdk driver with rdma.
https://gerrit.fd.io/r/#/c/18521/
Which I used in the rpms for CentOS.
The challenge I had was that convincing dpdk to "see" the pci,
That was because the server boots with the mlx ints in a bond and after
removing the if from the bond,
I had to explicitly whitelist it in vpp.conf.
I don't know how to with the new ext rdma driver in 19.04 because it
doesn't make sense to white list it for dpdk.

Hi Thomas,
I just pushed a small doc:
https://gerrit.fd.io/r/c/19364/3/src/plugins/rdma/rdma_doc.md
I also tried:
vpp# create interface rdma name mlx5
create interface rdma: invalid interface (only mlx5 supported for now)
You are missing the 'host-if <netdev>' stanza, eg:
vpp# create int rdma host-if enp94s0f0 name mlx5
Here enp94s0f0 is the netdev of the mhysical port you want to use.
Here are my commands for 19.04

Let me know if you need more info.
