This information will be displayed when '-details' is provided by the user. Example: $ ip -d l l tun10 6: tun10: mtu 1480 qdisc noqueue state UNKNOWN mode DEFAULT link/sit 10.16.0.249 peer 10.16.0.121 sit remote 10.16.0.121 local 10.16.0.249 ttl inherit pmtudisc 6rd-prefix 2002::/16 promiscuity 2 Signed-off-by: Nicolas Dichtel --- diff --git a/ip/ipaddress.c b/ip/ipaddress.c index 2eb1a0a62..e8cab4092 100644 --- a/ip/ipaddress.c +++ b/ip/ipaddress.c @@ -464,6 +464,10 @@ int print_linkinfo(const struct sockaddr_nl *who, if (do_link && tb[IFLA_LINKINFO] && show_details) print_linktype(fp, tb[IFLA_LINKINFO]); + if (do_link && tb[IFLA_PROMISCUITY] && show_details) + fprintf(fp, "\n promiscuity %u ", + *(int*)RTA_DATA(tb[IFLA_PROMISCUITY])); + if (do_link && tb[IFLA_IFALIAS]) fprintf(fp,"\n alias %s", rta_getattr_str(tb[IFLA_IFALIAS]));
