One other thing that popped up in my head is how (will) it work

with DPDK enabled on the same system?
Why not?
I’m like if it’s not tested it’s not working…
It works OK with OVS-DPDK.
For example, I can create a br0, attach a af_xdp port and also attach
a dpdk port to it. (I tested using dpdk vhost port, not physical one).
The performance is lower than using two dpdk ports due to some packet
copying from one to another.
This is because to sent to the DPDK ports you use the shared queue which
might block on a mutex. Sending from a DPDK port to XDP might be worse,
as the PMD might stall due to the syscall required.
I’ll try to do some more tests on this combination once I return from
PTO.
