The fact that the MFP flag gets reset is pretty strange. It looks like mac80211 will only ever do this in response to an add/set station command, but authsae also only sets the MFP flag in conjunction with authorized and authenticated flags. Hmm. Is there any interesting dmesg output when this happens? authsae logs? > If I restart the mesh that has the negative variable in Toffset > every comes back online with ESTAB and traffic flows nicely. > and of course MFP turns to yes on both units. > > BTW using the latest builds from git. > > > Any assistance would be appreciated. > > Fred > > > > _______________________________________________ > Devel mailing list > [email protected] > http://lists.open80211s.org/cgi-bin/mailman/listinfo/devel > -- Thomas _______________________________________________ Devel mailing list [email protected] http://lists.open80211s.org/cgi-bin/mailman/listinfo/devel
