Re: [PATCH bpf-next v6 1/5] netfilter: defrag: Add glue hooks for enabling/disabling defrag

We want to be able to enable/disable IP packet defrag from core
bpf/netfilter code. In other words, execute code from core that could

To help avoid symbol resolution errors, use glue hooks that the modules
will register callbacks with during module init.
