Benjamin Berg 170cd6a66d wifi: mac80211: add netdev per-link debugfs data and driver hook
This adds the infrastructure to have netdev specific per-link data both
for mac80211 and the driver in debugfs. For the driver, a new callback
is added which is only used if MLO is supported.

Benjamin Berg e1f113cc67 wifi: mac80211: add pointer from bss_conf to vif
While often not needed, this considerably simplifies going from a link
specific bss_config to the vif. This helps with e.g. creating link
specific debugfs entries inside drivers.

Lorenzo Bianconi 9288188438 wifi: mac80211: move color collision detection report in a delayed work
Move color collision report in a dedicated delayed work and do not run
it in interrupt context in order to rate-limit the number of events
reported to userspace. Moreover grab wdev mutex in
ieee80211_color_collision_detection_work routine since it is required
by cfg80211_obss_color_collision_notify().

Johannes Berg 9b41a9d7dc wifi: mac80211: recalc station aggregate data during link switch
During link switching, the active links change, so we need to
recalculate the aggregate data in the stations.

Johannes Berg 3d90110292 wifi: mac80211: implement link switching
Implement an API function and debugfs file to switch
active links.

Also provide an async version of the API so drivers
can call it in arbitrary contexts, e.g. while in the
authorized callback.

Johannes Berg efe9c2bfd1 wifi: mac80211: isolate driver from inactive links
In order to let the driver select active links and properly
make multi-link connections, as a first step isolate the
driver from inactive links, and set the active links to be
only the association link for client-side interfaces. For
AP side nothing changes since APs always have to have all
their links active.

To simplify things, update the for_each_sta_active_link()
API to include the appropriate vif pointer.

This also implies not allocating a chanctx for an inactive
link, which requires a few more changes.

Since we now no longer try to program multiple links to the
driver, remove the check in the MLME code.

Johannes Berg e73b5e51a0 wifi: mac80211: move link code to a new file
We probably should've done that originally, we already have
about 300 lines of code there, and will add more. Move all
the link code we wrote to a new file.
