2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-10/+16
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.

2019-12-20vxlan: reuse inner packet flow hash for tunnel outer header load balanceShawn Ji1-0/+7
Type: fix Several tunnels encapsulation use udp as outer header and udp src port is set by inner header flow hash, such as gtpu, geneve, vxlan, vxlan-gbd Since flow hash of inner header is already been calculated, keeping it to vnet_buffere[b]->ip.flow_hash should save load-balance node work to select ECMP uplinks.

2019-03-26Simplify adjacency rewrite codeBenoît Ganne1-18/+5
Using memcpy instead of complex specific copy logic. This simplify the implementation and also improve perf slightly. Also move adjacency data from tail to head of buffer, which improves cache locality (header and data share the same cacheline) Finally, fix VxLAN which used to workaround vnet_rewrite logic.
