The title is still misleading 

Changed to 

" add raw format for 32 bytes Rx description"

> The purpose of this commit is sync with latest share code.

Changed to

"Add raw format for i40e_32byte_rx_desc, right now this only be used
by kernel driver, the commit is just to sync with kernel driver"
