Hi all, I found the problem. There is a check in /net/mac80211/cfg.c !rcu_access_pointer(sdata->bss->beacon)) I guess this related to beaconing. If it is not configured, off-channel is required in any case. If you put the interface into AP mode and try to send frames with NL80211_CMD_FRAME you have to set the OFFCHANNEL_TX_OK flag in any case !!! Right now I am facing the problem of not getting probe-requests delivered to my master mode interface through NL80211_CMD_REGISTER_FRAME. It works only if I start an additional monitor interface on the same card. Any clue what to do to enable frame delivery to the AP interface without a monitor interface.
