Current implementation of NL80211_CMD_GET_STATION does not work
for multi-link operation(MLO) since in case of MLO only deflink
(or one of the links) is considered and not all links.
Hence, add the link_sinfo structure to provide infrastructure
for link-level station statistics for multi-link operation(MLO).
Additionally, accumulated stats for MLO are included in a concise
manner to provide a comprehensive overview of the ML stations.
V3:
- Convert RFC patch to actual PATCH with each patch bisectable.
- Add logic for MLO level signal and rates.
V2:
- Update cover letter to give more details on structural changes.
- Split the patch(1/7) in two patches.
- Do the required changes for MLO bringup before as seperate patches.
- Remove link_sinfo naming to sinfo for better clarity on changes.
- Add accumulated stats logic in cfg80211.
- Add flag to indicate driver supports per-link station statistics or not.
Current flow:
cfg80211:
- Structure station_info is used to fill all station information (station
level as well link level).
- Nl80211_get_station() - locally define sinfo, call -.get_station() ops
mac80211:
- Sta_set_sinfo() - fill station information and call mac80211
ops - .sta_statistics()(to fill the station_info structure).
Purposed flow:
cfg80211:
- Structure changes for station_info
structure station_info {
filled
packets
sta_flags
... etc // station specific fields
link_station_info *links[IEEE80211_MLD_MAX_NUM_LINKS]
}
structure link_station_info {
filled
rates
...etc // all link specific fields
}
- Split station_info structure into station specific and link specific
fields- (station_info and link_station_info).
- Add array pointers in station_info structure for link_station_info.
for non-ML use links[0], for ML use *links for each valid links.
- Nl80211_get_station() - locally define sinfo, call -.get_station() ops.
- Once link station information filled, fill mld level information in
cfg80211_sta_set_mld_sinfo() for MLO.
- Introduce a flag to indicate if driver provides per-link station
statistics or not and embed NL attributes accordingly.
mac80211:
- Sta_set_sinfo() - fill station specific information and call
sta_set_link_sinfo()
a. If MLO and driver provides per-link statistics
- For each link fill link specific data in *links[link_id]
- Call mac80211 ops for each link- .link_sta_statistics() to
fill link statistics.
b. If non-ML or driver does not provides per-link statistics
- Fill link level data for links[0]
- Call mac80211 ops- .link_sta_statistics() to fill link statistics
- Maintain accumulated data for removed links in sta_info structure
and fill in to station_info structure for consistency.
