This is to test the behaviour of L2CAP channel when closed with
shut_down(sock, SHUT_WR). In this case, we should wait until we
receive a disconnection response before raising G_IO_HUP.

Hi Marcel,
I add a new test in l2cap-tester that specifically tests for "when
closing socket, wait until we receive disconnection reply before
closing". This will only work if we close with SHUT_WR and after the
corresponding kernel patch (https://lkml.org/lkml/2020/4/22/1564) is
applied.
Is this the test that you have in mind?

Id make the test abort if cannot be disconnected properly, but it
looks like we don't have any means to detect if the kernel has support
for it or not, but perhaps it is fine since this is trying to test the
right behavior.

Yeah, currently we have no way of knowing whether the kernel supports
this behavior or not. If we really want to, perhaps we can add
something to query that, but I doubt that is worth the hassle.
