> Subject: [Intel-wired-lan] [PATCH net-next 2/8] iavf: extract 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 iavf with the new
> ethtool API for querying RX ring parameters.
