How do you know that the peer does not use the same dialog token again
for the next GO Negotiation? Please keep in mind that the peer may be
using different implementation.. In addition, there could be cases where
our GO Negotiation Response is lost and peer tries to send GO
Negotiation Request again. As such, I'm not sure this is really a
suitable way of working around this.
Furthermore, I'm not completely sure what exactly you are trying to work
around. The changing SSID? Didn't commit
4458d91554cce6c8a78916701c2701162cbbfad1 already take care of that?
