RFC on per-link stats reporting.

[Ben Greear <greearb@xxxxxxxxxxxxxxx>]

Hello,

While trying to better understand how MLO was working, I started
on some code to gather stats from the driver so that mac80211 has
visibility into it.


In particular, I added a small struct to hold per-link stats for up to 3 links
to the station_info struct.  Then in the driver, I gather the available info
when mac80211 asks for the station info.


#define IEEE80211_MAX_STA_INFO_LINK 3
/**
 * struct station_info_link -- Link info
 *
 * Same definitions as in station_info, but for links.
 */
struct station_info_link {
	u64 filled;
	s8 rx_beacon_signal_avg;
	struct rate_info txrate;
};

struct station_info {
....
	struct station_info_link link_info[IEEE80211_MAX_STA_INFO_LINK];
}

Is there any interest in this approach for the upstream kernel?

Thanks,
Ben
