Merge tag 'nf-25-09-04' of https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf
Florian Westphal says:
====================
netfilter: updates for net
1) Fix a silly bug in conntrack selftest, busyloop may get optimized to
for (;;), reported by Yi Chen.
2) Introduce new NFTA_DEVICE_PREFIX attribute in nftables netlink api,
re-using old NFTA_DEVICE_NAME led to confusion with different
kernel/userspace versions. This refines the wildcard interface
support added in 6.16 release. From Phil Sutter.
