2016-11-12pseudo atomic adjacency updatesNeale Ranns10-94/+230
When an adjacency changes from incomplete to complete (arp to rewrite) and vice-versa, that update must produce valid behavour w.r.t. the packets that continue to encounter it. Change-Id: Icc2709aff9807c5d24f91ef7649268991ad9a45d Signed-off-by: Neale Ranns <nranns@cisco.com>

2016-11-10VXLAN tunnel encap forwarding optimization with FIB 2.0John Lo7-370/+490
Optimize VXLAN encap node so that vxlan4-encap node is used for IP4 and vxlan6-encap node is used for IP6 underlay. Also stack the VXLAN encap nodes to the appropriate FIB IP4 or IP6 load-balance node instead of ip4/ip6-lookup node to save IP lookup operation. For VXLAN decap node, check VXLAN header FLAGS field for each packet and remove the code to support decap-next for IP4 or IP6. These decap- next values were intended for experimentation purposes and not needed any more since VXLAN-GPE tunnel is supported. The decap-next field is still kept in API for backward compatibility and its value has no effect. Decap next for both vxlan4-decap and vxlan6-decap nodes is always l2-input node.

An issue is that the server->server_fib_index is overwritten by some incorrect value on subsequent calls to the function - e.g. when setting DHCP proxy for the same FIB table several times.

2016-11-09devices: create dummy device-input node to keep nexts in syncDamjan Marion11-29/+31
device-input feature arc requires that all input-nodes have nexts in sync. packet-generator tends to call vlib_node_add_next when new stream is created and that puts nexts out of sync. With this change all input node are siblings of device-input node so call to vlib_node_add_next(...) will install same next to the whole family.

2016-11-07Fix dual-loop issue in vxlan_gpe decapHongjun Ni1-18/+24
From logical point, if first packet is ipv4, and second packet is ipv6. When first packet failed, the procedure will skip key6_1 setting. This will lead to second packet's failure. But here the graph node only process either ipv4 or ipv6 packets completely. So it is not an issue here. This patch only make the packet processig's logic clear. It is just a cosmetic change.
