From: Rafał Miłecki <rafal@xxxxxxxxxx>
Some features supported by firmware aren't advertised and there is no
way for a driver to query them. This includes e.g. monitor mode details.
Some firmwares support tagging monitor frames, some build radiotap
header but there is no way to detect it.
This commit adds table that will allow specifying features like:
{ "01-abcdef01", BIT(BRCMF_FEAT_FOO) }
