[Pkg-bluetooth-maintainers] Bug#514980: Workaround

[moriel]

Hi again.

Though I didn't find a real solution for my problem, I found a nice & 
simple workaround, which may be useful to further track down the problem.

Setting MTU on the bnep0 interface of my notebook to a value of 800 or 
less (ifconfig bnep0 mtu 800) completely removes all connection issues. 
Furthermore, I can easily achieve transfer rate of up to 1,5Mbps. 
Setting MTU to higher than 1000 immediately restores the "connection 
freezing" problem. The max "working" value of MTU should be therefore 
somewhere between 800 and 1000.

I remember there was a similar problem a few months ago with some linux 
routers, which didn't correctly work with tcp_window_scaling enabled. 
Some servers (webpages) could be accessed, some couldn't.

I can only guess here, but perhaps there is a problem with bnep 
encapsulation?

Best regards
Marcin
