I don't think so, those messages are usually an indicator for a successful 
connection. AP sends those as a 'hello, i'm still here' kinda thing. You 
should be able to supress those with 'wlandebug 0xffffffff -dumppkts'.

If you can get debug output while the UPs/DOWNs happen, that would help a lot.
