Out of code snippets you provided, looks like it is SR related. So might be worth adding existing code author(s) to CC, as maybe they are not reading this list very frequently. “git blame” might be useful for finding right names.

We faced issues compared to AD2 (Eth) functionality testing and following is the summary For AD2: In Egress packets are getting received from VM’s (QEMU VM) vhost-user-input which is sibling of device-input For AD4: In Egress packets are getting received from vhost-user-input, so here packets are going to ethernet-input node which are received from virtual interface and pkt is getting dropped in Ethernet because of wrong mac. As the AD4 feature is enabled in ip4-unicast arc, packets are dropped even before coming to this arc. /* *INDENT-OFF* */ VNET_FEATURE_INIT (srv6_ad2_rewrite, static) = { .arc_name = "device-input", .node_name = "srv6-ad2-rewrite", .runs_before = VNET_FEATURES ("ethernet-input"), }; VNET_FEATURE_INIT (srv6_ad4_rewrite, static) = { .arc_name = "ip4-unicast", .node_name = "srv6-ad4-rewrite", .runs_before = 0, }; We have modified the code to receive the packet from device-input as below VNET_FEATURE_INIT (srv6_ad4_rewrite, static) = { .arc_name = "device-input", .node_name = "srv6-ad4-rewrite", .runs_before = 0, }; After this change, we see its working fine, wish to check if our observation fine along with code changes. Also we would like to know what setup you have used to act as VM ?? that is, whether you have used vhost-user-input for sending and receiving packets to/from VM respectively.
