2019-07-02gbp: add anonymous l3-out external interfacesBenoît Ganne1-0/+1
So far, GBP l3-out packets classification & policy relied on programmed EP. All traffic to/from l3-out must go through a known EP. This patch introduces a new feature where l3-out next-hops are only known by their subnets (l3-out prefixes). As there are no longer known EPs to program, an interface must be configured as external anonymous l3-out. Packets classification & policy on this interface will rely on the external subnets programmed in the BD VRF. Note that contrary to all other interfaces in a GBP BD, external anonymous l3-out interfaces have BD L2 learning turned on and rely on ARP/ND.

2018-10-15vnet: create L2 feature arc infrastructureAndrew Yourtchenko1-0/+1
This commit adds two new nodes in the L2 datapath in input and output direction respectively. These nodes fork the traffic into three feature arcs: ip4, ip6 and nonip, which later join to continue the usual L2 processing. The vnet_l2_feature_enable_disable() function with the same signature as vnet_feature_enable_disable() takes care of enabling the L2 datapath feature bits as needed, when the features are enabled/disabled. Thus, L2 features may use the similar plumbing as the L3 features enjoy. Change-Id: I76877b3a92d794c492bff1622bb26acba05705b2 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-04-24Support QOS_SOURCE_IP recording from L2 input node.Igor Mikhailov (imichail)1-0/+1
Some scenarios not involving ip[4,6]-input paths might benefit from IP header QOS fields recorded and applied. An example: L2 (overlay) traffic being encapsulated by VPP in VXLAN and transmitted on another (underlay) interface might want the QOS information carried over in the outer IP header.

2017-12-20L2 EmulationNeale Ranns1-0/+1
L2 Emulation is a feautre that is applied to L2 ports to 'extract' IP packets from the L2 path and inject them into the L3 path (i.e. into the appropriate ip[4|6]_input node). L3 routes in the table_id for that interface should then be configured as DVR routes, therefore the forwarded packet has the L2 header preserved and togehter the L3 routed system behaves like an L2 bridge.

Allow non-static MACs in the L2FIB which is associated with an interface or a bridge domain (BD) be flushed.
