tadata. vxlan driver will lookup forwarding database with (mac + vni) for the required remote destination information to forward the packet. Changes introduced by this patch: - allow learning and forwarding database state in vxlan netdev in COLLECT_METADATA mode. Current behaviour is not changed by default. tunnel info flag IP_TUNNEL_INFO_BRIDGE is used to support the new bridge friendly mode. - A single fdb table hashed by (mac, vni) to allow fdb entries with multiple vnis in the same fdb table - rx path already has the vni - tx path expects a vni in the packet with dst_metadata - prior to this series, fdb remote_dsts carried remote vni and the vxlan device carrying the fdb table represented the source vni. With the vxlan device now representing multiple vnis, this patch adds a src vni attribute to the fdb entry. The remote vni already uses NDA_VNI attribute. This patch introduces NDA_SRC_VNI netlink attribute to represent the src vni in a multi vni fdb table. iproute2 example (patched and pruned iproute2 output to just show relevant fdb entries): example shows same host mac learnt on two vni's. before (netdev per vni): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan1000 dst 12.0.0.8 self after this patch with collect metadata in bridged mode (single netdev): $bridge fdb show | grep "00:02:00:00:00:03" 00:02:00:00:00:03 dev vxlan0 src_vni 1001 dst 12.0.0.8 self 00:02:00:00:00:03 dev vxlan0 src_vni 1000 dst 12.0.0.8 self Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David S.

Miller <davem@davemloft.net> 2017-02-03Merge branch 'ife-to-module'David S. Miller13-90/+276 Yotam Gigi says: ==================== Extract IFE logic to module Extract ife logic from the tc_ife action into an independent module, and make the tc_ife action use it. This way, the ife encapsulation can be used by other modules other than tc_ife action. v1->v2: Fix duplicate symbol error by introducing a new patch that makes the original symbol static. The symbol ife_tlv_meta_extract is exported in act_ife, though not being used by any other module. As the symbol is being moved to the new ife module, introducing the new module creates duplicate symbol. To fix it, add a new patch (1/3) that makes the ife_tlv_meta_extract symbol static in act_ife, thus the symbol does not collide. ==================== Signed-off-by: David S.
