Please add fix line and Cc stable.
Fixes: 73cd7d6dc8e1 ("net/i40e: use set switch AQ instead of register setting")

> 
> FW4.16 of SFP X722 does not support setting TPID by set_switch_config
> adminq operation, for firmware version less than 4.16 TPID is set by register
> instead. For device SFP X722, disable adminq flag to follow the same path with
> old firmware version to make it work.

> Unset adminq flag instead of only checking device id when set TPID.
> v1
> Check device id when setting TPID, use adminq if not SFP X722, else use
> register.
