Merge branch 'selftest-netfilter-additional-cleanups'
Florian Westphal says: ==================== selftest: netfilter: additional cleanups This is the last planned series of the netfilter-selftest-move. It contains cleanups (and speedups) and a few small updates to scripts to improve error/skip reporting. I intend to route future changes, if any, via nf(-next) trees now that the 'massive code churn' phase is over. ==================== Link: https://lore.kernel.org/r/20240423130604.7013-1-fw@strlen.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>
