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.
