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:
v8:
Restrict length == 0 and proto_hdr == 0 in another buffer split.
Add check for proto_hdr == 0 in last segment.
Use heap instead of stack for array to avoid vulnerabilities.
Define the proto_hdr for two segments and multi-segments, respectively.
Separate variable definition and code.
Refine the doc and commit log.
Overall LGTM, please, process review notes and I think it will
be ready to be accepted.
