CAP_ACK means: trim off the payload that the netlink error message
is embedding, just like ICMP error does.

What is exactly your concern? If the user explicitly requests this
via socket option for this socket, then we're expecting they do the
right handling for what they're asking for.

I think David's concern was that when you want to parse the ACK in a
library (or application), you may not easily know if the application
(or library) requested capping.

exactly.
