> 
> In current implementation default VSI switch filter is only able to forward
> traffic to a single VSI. This limits promiscuous mode with private flag 'vf-true-
> promisc-support' to a single VF. Enabling it on the second VF won't work. Also
> allmulticast support doesn't seem to be properly implemented when vf-true-
> promisc-support is true.
> 
> Use standard ice_add_rule_internal() function that already implements
> forwarding to multiple VSI's instead of constructing AQ call manually.
> 
> Add switch filter for allmulticast mode when vf-true-promisc-support is
> enabled. The same filter is added regardless of the flag - it doesn't matter for
> this case.
> 
> Remove unnecessary fields in switch structure. From now on book keeping
> will be done by ice_add_rule_internal().
> 
> Refactor unnecessarily passed function arguments.
> 
> To test:
> 1) Create 2 VM's, and two VF's. Attach VF's to VM's.
> 2) Enable promiscuous mode on both of them and check if
>    traffic is seen on both of them.
