From: Ben Greear <greearb@xxxxxxxxxxxxxxx> I saw a case where the kernel's nl80211 rejected hostapd's attempt to send a neighbor report response because nl80211 flagged the frame as offchannel-OK, but kernel rejects because channel was on ch 100 and so kernel failed thinking it was constrained by CAC. So, don't even set the packet as off-channel OK if we are not transmitting offchannel.
