Question: Check if nf_tables is initialized

[sbezverk]

What would you suggest to use to check if nf_tables module is loaded from the go code. I mean other that executing external lsmod and grep for nf_tables?
Appreciate your thought about it.

AFAIR, if you open the netlink socket (e.g. via the nftables library), you’ll get something like ENOSYS error code if nftables is not available in the kernel. Have you looked at that? I think that’ll be much more robust than relying on external programs.
