How about you start reading the emails that you receive rather than
seemingly insisting that I somehow fix the Linux networking stack -
which would involve me talking to someone who has publically tried
to oust me from being ARM maintainer, and whom would probably reject
any attempt to fix this _because_ I was the person involved in proposing
the fix?

It's far better that someone else sorts this out, they are much more
likely to get a favourable response.
