We should try to have this kind of feature better supported across every drivers.
[Shahaf Shuler] there is a patch we are pushing which will enable to read the xstats from a secondary process:

[Shahaf Shuler] DPDK secondary process much conflict with Mellanox Arch. we will put this task on our plans.
