Previously we would check in nl80211 with an empty
cfg80211_wowlan structure to check for 'iw phy phyX wowlan enable'
with empty arguments (or) no triggers and disable WoWLAN.
No ... that's not how it works. If you enable WoWLAN without any
triggers, then that's what you get: the connection is kept alive but
there are no wakeup sources. If you don't specify the triggers at all
then it's disabled.
If we want to do disable WoWLAN we can use the command 'iw phy phyX
wowlan disable' command. Its true that we would 'Keep Alive'
the connection, but we would disable the wake up capability via
'set_wakeup' callback, something similar to wowlan disable command.
Please let me know if i am missing something (or) the advantage having
the connection Keep alive with wowlan enable without triggers.
I don't know if there's any advantage. It could be useful for example to
get a connection up quicker after resume. I just didn't want to preclude
that use case.
oh, ok fine.
