Tom,
perused the thread and it seems you are serious ;->
Are we heading towards Frankenstein Avenue?
The whole point behind letting in XDP is so that _small programs_
can be written to do some quick thing. eBPF 4K program limit was
touted as the check and bound. eBPF sounded fine.
This sounds like a huge contradiction.

Hi Jamal,
I don't understand why you think this is so controversial. The way I
see it (after reading the thread): This is about allowing kernel
components to _also_ use the XDP hook.
The initial push was XDP to support very small programs that did
very simple things fast (to be extreme: for example running a whole
network stack is a no-no). EBPF with the 4K program limit was pointed
as the limit.
What Tom is presenting is implying this constraint is now being
removed. Thats the controversy.
cheers,
jamal
