2021-05-05vlib: move offload flags to 1st cacheline in vlib_buffer_tMohsin Kazmi1-2/+2
Type: improvement Some tests i.e. ipsec see performance regression when offload flags are moved to 2nd cacheline. This patch moves them back to 1st cacheline. Change-Id: I6ead45ff6d2c467b0d248f409e27c2ba31758741 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-7/+9
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang1-12/+30
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 Zavaritsky1-54/+21
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.
