This should -help tease out bugs associated with queueing up packets from different -cores in parallel. Currently, it hasn't found those types of bugs, but -given future planned work, this is a useful regression to avoid. - -Fixes: e7096c131e51 ("net: WireGuard secure network tunnel") -Signed-off-by: Jason A.
