Please can you reconsider the patch regarding the accept_queue
http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.22.git;a=commit;h=8488df894d05d6fa41c2bd298c335f944bb0e401
It disallows to set a `backlog' argument to listen(2) of zero. Using
a zero backlog is often done (e.g. ttcp), and disallowing a zero
backlog will break many applications. I had to recode several applications
which rely on this convention.
The problem further spreads from TCP to DCCP (same behaviour).
Below is a patch to revert this change.
Thank you
