Subject: [PATCH net-next 0/2] net: broadcom: migrate to
 .get_rx_ring_count() ethtool callback

This series migrates Broadcom ethernet drivers to use the new
.get_rx_ring_count() ethtool callback introduced in commit 84eaf4359c36
("net: ethtool: add get_rx_ring_count callback to optimize RX ring
queries").

This change simplifies the .get_rxnfc() implementation by
extracting the ETHTOOL_GRXRINGS case handling into a dedicated callback,
making the code cleaner and aligning these drivers with the updated
ethtool API.

The series covers two Broadcom drivers: bnxt and bcmgenet. Each patch
removes the ETHTOOL_GRXRINGS case from the driver's .get_rxnfc() switch
statement and implements the new .get_rx_ring_count() callback that
returns the number of RX rings.
