--- Comment #1 from Michal Krawczyk (mk@semihalf.com) ---
Hi Amiya,

this is associated with lack of the proper MP support of the older ENA PMD =
(it
supports MP properly starting from DPDK v22.03).

The xstats API uses ENA admin queue in DPDK v20.11, and admin queue cannot =
be
used safely from the secondary process.

Those commits were improving the MP support starting from v20.11 to v22.03:

net/ena: make ethdev references multi-process safe
aab58857330bb4bd03f6699bf1ee716f72993774

net/ena: disable ops not supported by secondary process
39ecdd3dfa15d5ac591ce8d77d362480bff32355

net/ena: proxy AQ calls to primary process (this is the critical patch)
e3595539e0e03f0dbb81904f8edaaef0447a4f62

net/ena: enable stats for multi-process mode
3aa3fa851f58873457bdc5c387d0e5956f812322

net/ena/base: make IO memzone unique per port

Thanks,
Michal
