From 6809538e646bf86c000dc1faba60b0a4157ad898 Mon Sep 17 00:00:00 2001 From: Mohsin Kazmi Date: Wed, 10 Feb 2021 11:26:24 +0100 Subject: vlib: refactor checksum offload support 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.
