I have just a few small patches in this tree, so probably not my fault :)

 From this code in reg.c:

/*
  * Restoring regulatory settings involves ingoring any
  * possibly stale country IE information and user regulatory
  * settings if so desired, this includes any beacon hints
  * learned as we could have traveled outside to another country
  * after disconnection. To restore regulatory settings we do
  * exactly what we did at bootup:
  *
  *   - send a core regulatory hint
  *   - send a user regulatory hint if applicable
  *
  * Device drivers that send a regulatory hint for a specific country
  * keep their own regulatory domain on wiphy->regd so that does does
  * not need to be remembered.
