[PATCH net-next v4 4/8] net: macb: use the current queue number for stats

From: Paolo Valerio <hidden>
Date: 2026-03-09 14:44:18
Subsystem: atmel macb ethernet driver, networking drivers, the rest · Maintainers: Théo Lebrun, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

gem_get_ethtool_stats calculates the size of the statistics
data to copy always considering maximum number of queues.

The patch makes sure the statistics are copied only for the
active queues as returned in the string set count op.
