To: netfilter-devel; +Cc: Florian Westphal
Try to attach ct templates at various priorities and check that
attachmet only works at the acceptable positions: prerouting + output,
before nf_conntrack_in() on the kernel side.
Relax the test for now to not fail on kernels that lack the required
validation and SKIP if all attachment request work.

Companion nftables.git shell test for the
'netfilter: nft_ct: validate hook and priority for ct zone set' kernel
patch.
It could be added to nftables.git already, its expected to PASS or
SKIP only.
