Protocol type based buffer split consists of splitting a received packet
into several separate segments based on the packet content. It is useful
in some scenarios, such as GPU acceleration. The splitting will help to
enable true zero copy and hence improve the performance significantly.
This patchset aims to support protocol header split based on current buffer
split. When Rx queue is configured with RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT
offload and corresponding protocol, packets received will be directly split
into different mempools.
Change log:
v9:
Define the intend behaviors for exact match and longest match.
Add protocol headers repeat check.
Add no proto-split after length-based split check.
Add a helper function to short the check function.
Refine the doc and commit log.
With few minor fixes, applied to dpdk-next-net/main, thanks.
