If I'm, not mistaken, this function is invoked as part of the execute_controller_action - I'm not too familiar with this action, could you provide an example of how it is used in this context? > new_buffer->cutlen = buffer->cutlen; > #ifdef DPDK_NETDEV > new_buffer->mbuf.ol_flags = buffer->mbuf.ol_flags; >+ new_buffer->mbuf.tx_offload = buffer->mbuf.tx_offload; >+ new_buffer->mbuf.packet_type = buffer->mbuf.packet_type; >+ new_buffer->mbuf.nb_segs = buffer->mbuf.nb_segs; > #else > new_buffer->rss_hash_valid = buffer->rss_hash_valid; > #endif >diff --git a/lib/netdev-dpdk.c b/lib/netdev-dpdk.c >index ddc651b..ba044a3 100644 >--- a/lib/netdev-dpdk.c >+++ b/lib/netdev-dpdk.c >@@ -1764,6 +1764,10 @@ dpdk_do_tx_copy(struct netdev *netdev, int qid, struct >dp_packet_batch >*batch) > memcpy(rte_pktmbuf_mtod(pkts[newcnt], void *), > dp_packet_data(batch->packets[i]), size); > >+ pkts[newcnt]->nb_segs = batch->packets[i]->mbuf.nb_segs; >+ pkts[newcnt]->ol_flags = batch->packets[i]->mbuf.ol_flags; >+ pkts[newcnt]->packet_type = batch->packets[i]->mbuf.packet_type; >+ pkts[newcnt]->tx_offload = batch->packets[i]->mbuf.tx_offload; If packet comes from a non-DPDK source, are these fields of any value? > rte_pktmbuf_data_len(pkts[newcnt]) = size; > rte_pktmbuf_pkt_len(pkts[newcnt]) = size; > >-- >1.8.3.1 _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
