> If there's VF reset, the kernel PF will remove rules
> associated with the reset VF no matter the HW VSI ID
> is changed or not. So DCF should redirector all rules
> associated with the reset VF no matter the HW VSI ID
> is changed or not.

> Fixes: f10cde8e8478 ("net/ice: get VF hardware index in DCF")
> Fixes: dc0f06849e50 ("net/ice: redirect switch rule to new VSI")
