net80211: split scan_task() (#3) (into scan_start() and scan_curchan_task() functions)

Authored by avos on Jan 30 2016, 10:41 PM.



(This part should fix the problem, described in

  • Rename ss_scan_task into ss_scan_start (better describes it's current purpose)
  • Utilize taskqueue_*_timeout() functions instead of current mechanism:
    • reschedule scan_curchan_task() via taskqueue_enqueue_timeout() for every 'maxdwell' msecs (will replace infinite loop + sleeping for 'maxdwell' period via cv_wait());
    • rerun the task immediately when an external event occurs (instead of waking it up via cv_signal())

Also, use mtx_sleep() to wait for null frame transmission (allows to drop conditional variable).

Test Plan

Tested with:

  • Intel 3945BG, STA mode;
  • RTL8188EU, STA mode.
