The\nindication of whether a route is offloaded is done using the mfc_flags\nfield on an mfc_cache struct, and the information is sent to the userspace\nvia the RTNetlink interface only.\n\nCurrently, MFC routes are either offloaded or not, thus there is no need to\nadd per-VIF offload indication.\n\nSigned-off-by: Yotam Gigi <yotamg@mellanox.com>\nReviewed-by: Ido Schimmel <idosch@mellanox.com>\nSigned-off-by: Jiri Pirko <jiri@mellanox.com>\nReviewed-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>\n---\nv1->v2:\n - Add comment for the MFC_OFFLOAD flag\n---\n include/linux/mroute.h | 2 ++\n net/ipv4/ipmr.c | 3 +++\n 2 files changed, 5 insertions(+)", "diff": "diff --git a/include/linux/mroute.h b/include/linux/mroute.h\nindex 54c5cb8..5566580 100644\n--- a/include/linux/mroute.h\n+++ b/include/linux/mroute.h\n@@ -90,9 +90,11 @@ struct mr_table {\n \n /* mfc_flags:\n * MFC_STATIC - the entry was added statically (not by a routing daemon)\n+ * MFC_OFFLOAD - the entry was offloaded to the hardware\n */\n enum {\n \tMFC_STATIC = BIT(0),\n+\tMFC_OFFLOAD = BIT(1),\n };\n \n struct mfc_cache_cmp_arg {\ndiff --git a/net/ipv4/ipmr.c b/net/ipv4/ipmr.c\nindex ba71bc4..2a795d2 100644\n--- a/net/ipv4/ipmr.c\n+++ b/net/ipv4/ipmr.c\n@@ -2268,6 +2268,9 @@ static int __ipmr_fill_mroute(struct mr_table *mrt, struct sk_buff *skb,\n \t nla_put_u32(skb, RTA_IIF, mrt->vif_table[c->mfc_parent].dev->ifindex) < 0)\n \t\treturn -EMSGSIZE;\n \n+\tif (c->mfc_flags & MFC_OFFLOAD)\n+\t\trtm->rtm_flags |= RTNH_F_OFFLOAD;\n+\n \tif (!(mp_attr = nla_nest_start(skb, RTA_MULTIPATH)))\n \t\treturn -EMSGSIZE;\n \n", "prefixes": [ "net-next", "v3", "05/12" ] }
