Details - netifd sets the packet steering for all interfaces it controls to better spread the load over multiple cores. But it fails to set it for wds interfaces like wlan0.sta1. As result, the performance in WDS setups is limited by a single core of a multi-core device.

To reproduce: enable an AP in /etc/config/wireless. Enable the wds option for the AP interface. Connect a client to the AP and check /sys/devices/*****/net/wlan*.sta1/queues/rx-*/rps_cpus. All BITS for all available CPUs should be enabled (when it would work). It stays currently at 0.
