Hi Shibin

As I've already explained in my previous email, they are constant ATM, 
however they will become configurable. I am implementing the Operator 
and it will make a lot of these "fixed" params configurable. My 
recommendation is not to try to generate the path in DPDK - as it's 
likely to be different in different k8s environments.

As I've also mentioned, the current patch means that I don't need to 
come back in 2 months and update DPDK to support n paths for the UDS 
(aka future-proofing).

Additionally - this is a side discussion as far as this patch goes. *The 
point of this patch is to fix the broken UDS behavior *and it has been 
tested in a full deployment scenario. @Shibin if you strongly feel that 
there's a better approach, then please go ahead, implement it, test it 
in a full deployment scenario and push it for review.

In general, allowing the AF_XDP params to be configurable rather than 
fixing/hardcoding anything in DPDK decouples the AF_XDP DP from DPDK so 
we don't have to keep coming back to make changes.

BR
Maryam
