In previous release we already switched the queue management ops (for Rx zero-copy) to the instance lock. This series converts other ops to depend on the instance lock when possible. Unfortunately queue related state is hard to lock (unlike NAPI) as the process of switching the number of queues usually involves a large reconfiguration of the driver. The reconfig process has historically been under rtnl_lock, but for drivers which opt into ops locking it is also under the instance lock. Leverage that and conditionally take rtnl_lock or instance lock depending on the device capabilities. v1: https://lore.kernel.org/20250407190117.16528-1-kuba@kernel.org ==================== Link: https://patch.msgid.link/20250408195956.412733-1-kuba@kernel.org Signed-off-by: Jakub Kicinski --- f8cb38c32eb1ba14f82226bee1825e67cffe432f
