static int rtl8xxxu_set_rts_threshold(struct ieee80211_hw *hw, u32 rts)
Monitor mode is enabled by handling the filter flags we get from mac80211 in rtl8xxxu_configure_filter() and writing them to the RCR register. By handling the filters, we can also stop setting the BSSID filters in the association event.
