I haven't, but I don't think it would help either. The messages sent by
wpa_supplicant for clients that never receive them seem to be stuck
indefinitely and making the limit larger will just push out the
inevitable issue a bit further. If there were a way to make kernel drop
these eventually on some timeout that would obviously be helpful, but
I'm not sure what that would be for unconnected AF_UNIX datagram socket.
