This includes e.g. monitor mode details. - -Most firmwares support monitor interface but only the latest ones -/announce/ it with a "monitor" flag in the "cap" iovar. There isn't any -reliable detection method for older firmwares (BRCMF_C_MONITOR was tried -but "it only indicates the core part of the stack supports"). - -Similarly support for tagging monitor frames and building radiotap -headers can't be reliably detected for all firmwares. - -This commit adds table that allows mapping features to firmware version. -It adds mappings for 43602a1 and 4366b1 firmwares from -linux-firmware.git.
