I looked in the driver_nl80211.c and found that use_monitor relied on "poll_command_supported" and "data_tx_status". I printed these 2 parameters and saw that data_tx_status=0, it depends on >>NL80211_FEATURE_SK_TX_STATUS and this parameter was affected to the flags of wiphy->features, defined in /net/mac80211/main.c.I find this parameter was set = 0 in /backport-include/linux/nl80211.h >>> That's why montior mode was forced to used with AP mode.

Thing that I've changed concern the backport, I disable monitor interface in AP mode to solve the connection problem in a channel using DFS and it doesn't concern your firmware. Thanks for the confirmation. I haven't tested bridged networks yet, but maybe you were hitting some more general firmware problem that I had already fixed.
