Hi Daryl,

actually I learned that hcidump can't deal with the hint bit and that it
don't understand the QoS option. Both is fixed in CVS and looks now like
this:

> L2CAP(s): Config req: dcid 0x0040 flags 0x0001 clen 4
  [MTU 672] 
< L2CAP(s): Config rsp: scid 0x0040 flags 0x0001 result 0 clen 0
> L2CAP(s): Config req: dcid 0x0040 flags 0x0000 clen 28
  [FlushTO 65535] [QoS 0x01 (Best effort)] 
< L2CAP(s): Config rsp: scid 0x0040 flags 0x0000 result 0 clen 0

We send two empty resposonses, but from my current understanding this is
fine. All of the options have set the hint bit (indicated by []). Maybe
I am missing something, but the specification says:

	option is a hint; if the option is not recognized then
	skip the option and continue processing

So our responses are valid, because we answer both requests.

For you it is the best to go with the hack, because I don't think that I
will backport such a change to the 2.4 kernel series.

However do you also have a hcidump from that test for me?
