I apologize for email duplication, but it looks like reply from Vasily has been rejected due to Outlook issues. While we choose between mutt and gnus, here I briefly repeat the rationale behind these RFC patches. The nl80211 get_beacon callback appears to be useful in the case when userspace software needs to retrieve current operational parameters of AP including HT/VHT IEs. In fact we considered two implementation options: to implement this functionality either in hostapd (extending its hostapd_cli interface) or in kernel (adding nl80211 call). We decided to try nl80211 since there was a stub for NL80211_CMD_GET_BEACON operation. Beacon change notifier was introduced due to the following reason: if anyone is interested in AP operational params, then he might be also interested to know when those params are changed.
