> Subject: [PATCH] net/i40evf: fix packet loss issue for X722
>
> From: Beilei Xing <[email protected]>
>
> When Tx queue number is more than Rx queue number, and RSS is enabled,
> there'll be packet loss with X722.
> The root cause is the lookup table is not configured correctly, since it uses
> VF's queue pair number but not Rx queue number.
