Subject: [PATCH net-next v1] netfilter: nfnetlink: convert kfree_skb to consume_skb
Date: Tue, 28 May 2024 11:37:54 +0100	[thread overview]
Message-ID: <20240528103754.98985-1-donald.hunter@gmail.com> (raw)

Use consume_skb in the batch code path to avoid generating spurious
NOT_SPECIFIED skb drop reasons.
