>>	doc: add Rx buffer split limitation to mlx5 guide
>>	net/mlx5: report Rx buffer split capabilities
OK about above.

>>	net/mlx5: support Rx buffer split
It would be better: "net/mlx5: support Rx buffer split on datapath 

>>	net/mlx5: register multiple pool for Rx queue
OK

>>	net/mlx5: configure Rx buffer split
It would be better: "net/mlx5: configure Rx queue for buffer split"

>>	net/mlx5: receive Rx buffer split description
IMO, it would be better: "net/mlx5: handle Rx buffer split description"
or 
"net/mlx5: support Rx buffer split description"

Could you, please, also squash the hotfix:

Thanks in advance,
