Subject: [PATCH net-next 0/2] net: marvell: modernize RX ring count ethtool
 callbacks

This series converts the Marvell mvneta and mvpp2 drivers to use the new
.get_rx_ring_count ethtool operation, following the ongoing modernization
of the ethtool API introduced in commit 84eaf4359c36 ("net: ethtool: add
get_rx_ring_count callback to optimize RX ring queries").

The conversion simplifies the code by replacing the generic .get_rxnfc
callback with the more specific .get_rx_ring_count callback for retrieving
RX ring counts. For mvneta, this completely removes .get_rxnfc since it
only handled ETHTOOL_GRXRINGS. For mvpp2, the GRXRINGS case is extracted
while keeping other rxnfc handlers intact.

PS: These changes were compile-tested only.
