Ran xskxceiver's test suite via xsk.py runner on Intel E810-C (ice driver fw revision 4.70). It does not cover the duplicate fill ring entries but given the changes based on code inspection this run was to make sure I did not introduce any regressions around multi-buffer logic. > > Please do not repost the series just to address the above.
