4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ben Greear <greearb@xxxxxxxxxxxxxxx> commit 5c21e8100dfd57c806e833ae905e26efbb87840f upstream. This fixes stale beacon-int values that would keep a netdev from going up. To reproduce: Create two VAP on one radio. vap1 has beacon-int 100, start it. vap2 has beacon-int 240, start it (and it will fail because beacon-int mismatch). reconfigure vap2 to have beacon-int 100 and start it. It will fail because the stale beacon-int 240 will be used in the ifup path and hostapd never gets a chance to set the new beacon interval.
