As it turns out it can be read from /sys, but I do need it so I can know what to put in HWSIM_ATTR_ADDR_RECEIVER based on the destination addr in the frame or if I want to forward the frame to all radios.

Ok, I'll try that. get_wiphy_idx can stay in place, not sure if I should just drop it. By having *only* the wiphy index you don't mean dropping the radio names altogether? The don't seem useful but userspace may expect them. Best regards
