> GRXRINGS from .get_rxnfc
> 
> Commit 84eaf4359c36 ("net: ethtool: add get_rx_ring_count callback to
> optimize RX ring queries") added specific support for GRXRINGS
> callback, simplifying .get_rxnfc.
> 
> Remove the handling of GRXRINGS in .get_rxnfc() by moving it to the
> new .get_rx_ring_count().
> 
> This simplifies the RX ring count retrieval and aligns ixgbevf with
> the new ethtool API for querying RX ring parameters.
