Description Adrian Chadd freebsd_committer freebsd_triage 2016-04-08 23:40:07 UTC 
The ath(4) driver listens to all beacons on a channel, so it can do IBSS merges. This unfortunately means it also creates new node entries and attempts to do merges for IBSS networks with different SSIDs.

New revision: 297728
URL: https://svnweb.freebsd.org/changeset/base/297728

Log:
  [net8021] Pull out the ibss check code into a public function.

  The ath(4) driver now sees beacons and management frames for different
  BSSIDs in IBSS mode, which is a problem when you're in a very busy
  IBSS environment.

  So, expose this function so drivers can use it to check if the current
  RX node is actually for a BSS we need to pay attention to or not.
