Subject: [PATCH v2 2/5] bpf: use bulk free on filtered packets
Date: Fri, 31 Oct 2025 09:41:46 -0700 [thread overview]
Message-ID: <20251031164417.14166-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20251031164417.14166-1-stephen@networkplumber.org>
When rte_pktmbuf_free_bulk is faster because it does single
mempool operation rather than per-packet.
