2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang1-12/+31
This patch aims to improve decap performance by reducing expensive hash_get callings as less as possible using AVX512 on XEON. e.g. vxlan, vxlan_gpe, geneve, gtpu. For the existing code, if vtep4 of the current packet match the last vtep4_key_t well, expensive hash computation can be avoided and the code returns directly. This patch improves tunnel decap multiple flows case greatly by leveraging 512bit vector register on XEON accommodating 8 vtep4_keys. It enhances the possiblity of avoiding unnecessary hash computing once hash key of the current packet hits any one of 8 in the 512bit cache. The oldest element in vtep4_cache_t is updated in round-robin order. vlib_get_buffers is also leveraged in the meanwhile.

2020-03-03geneve gtpu vxlan vxlan-gpe: VRF-aware bypass nodeNick Zavaritsky1-40/+18
Bypass node MUST NOT intercept a packet if destination IP doesn’t match a local address. However IP address interpretation depends on the VRF, hence bypass node must take that into account. This patch also factors-out common VTEP management and checking code.

2017-10-06Initial GENEVE TUNNEL implementation and tests.Marco Varlese1-0/+1323
Notes on this first implementation: * First version of the implementation does NOT support GENEVE OPTIONS HEADER: it isn't well understood what the purpose of the OPTIONS will be and/or what content would be placed in the variable option data; Once the IETF work will evolve and further information will be available it could be possible to modify the frame rewrite to contemplate the actual GENEVE OPTIONS.
