It looks to me as a DPDK is= sue. I could see multiple fixes/patches in the net/ena area, but not able to identify which patch would exactly fix this issue. For example: http://git.dpdk.org/dpdk/diff/?h=3Dreleases&id=3Daab58857330bb4bd03f6699bf1= ee716f72993774 https://inbox.dpdk.org/dev/20210430125725.28796-6-mk@semihalf.com/T/#me9945= 7c706718bb236d1fd8006ee7a0319ce76fc Could you please help here and let me know what patch could fix this issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
