--- Comment #1 from Michal Krawczyk (m...@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,
