New Broadcom firmwares mark monitor mode packets using a newly defined
bit in the flags field. Use it to filter them out and pass to the
monitor interface. These defines were found in bcmmsgbuf.h from SDK.
As not every firmware generates radiotap header this commit introduces
BRCMF_FEAT_MON_FMT_RADIOTAP that has to be set per firmware version. If
not present brcmf_netif_mon_rx() assumed packet being a raw 802.11 frame
and prepends it with an empty radiotap header.
It's limited to the msgbuf protocol. Adding support for SDIO/USB devices
will require some extra research.

Hi Rafał,
I am preparing the 4366c0 release. Can you tell me which firmwares that
you have provide 802.11 packets and/or radiotap+802.11? Doing 'strings
fwfile | tail -1' should give me the necessary info.
Regards,
Arend
