> 
> This patch adds support for protocol based buffer split in normal Rx data
> paths. When the Rx queue is configured with specific protocol type, packets
> received will be directly split into protocol header and payload parts
> limitation of pmd. And the two parts will be put into different mempools.
> 
> Currently, protocol based buffer split is not supported in vectorized paths.
> 
> A new api ice_buffer_split_supported_hdr_ptypes_get() has been introduced,
> it will return the supported header protocols of ice PMD to app for splitting.
