May I also add a field such as "u16 active_links_count" in struct

like this ?:
if (active_links_count && hweight16(links) <= active_links_count)
then sdata->vif.active_links = links;
Also here, not sure it makes sense in cfg80211 level?
Though I'm not sure what the idea here is at all - you can refuse to
link switch etc, what would you use this for?
If I use ieee80211_set_active_links(),
then I need add BSS_CHANGED_ASSOC and key for 2nd link in lower-driver.
I would like to active all links while assoc,
then BSS_CHANGED_ASSOC and key will auto set for the 2nd link to
lower-driver from mac80211.
Then again, we haven't really designed out all the link selection stuff,
do we want wpa_s to do it, driver to do it, etc.? Hence debugfs. So
depending on what end up doing there, we will obviously need to
advertise some level of link-concurrency to userspace.
