2021-09-27gso: do not gro on small packetsAloys Augustin1-3/+41
This has two benefits: fix an issue where small packets can be padded to 64 bytes by the ethernet layer, and we included these bytes in the tcp stream; and also if we receive a small packet, it signals that this tcp stream is likely more latency-sensitive than throughput- sensitive, and skipping gro buffering should be beneficial.

2021-06-11gso: fix the gro re-ordering for packets with PSHMohsin Kazmi1-25/+54
Type: fix This prevents reordering when a push flag is received. GRO appends the segment with the push flag to the existing flow and flushes it immediately.

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-7/+6
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.
