There should be only one owner for the VF mac tables - either the DPDK or the Linux. If the DPDK is the owner, it should do the cleanup. If the sysadmin wants to be the owner then it should set the proper flag when running dpdk or alternatively not set the VF in trusted mode. > > Thanks, > > -- > Nélio Laranjeiro > 6WIND
