Re: [PATCH] mac80211-hwsim: add frequency attribute to netlink pkts

Hi Ben Johannes, while rebasing my hwsim patches on top of Ben's patches, I noticed that the freq attribute is not mentioned in hwsim_genl_policy struct. The same applies also to radio name and vif attributes. Just wondered should they be mentioned in the policy struct like the other attributes?
