> 
> This patch fixes the calculation of queue when we restore flow director filters
> after resetting adapter. In ixgbe_fdir_filter_restore(), filter's vf may be zero
> which makes the queue outside of the rx_ring array.
> 
> The calculation is changed to the same as ixgbe_add_ethtool_fdir_entry().
