Subject: [PATCH 0/2] Revert "veth: Avoid drop packets when xdp_redirect performs" and its fix
Date: Mon, 21 Nov 2022 19:28:46 +0800 [thread overview]
Message-ID: <20221121112848.51388-1-hengqi@linux.alibaba.com> (raw)
In-Reply-To: <eebf1c5ae11db046256eeb1aa287a0019adc3606.camel@redhat.com>
This patch 2e0de6366ac16 enables napi of the peer veth automatically when the
veth loads the xdp, but it breaks down as reported by Paolo and John. So reverting
it and its fix, we will rework the patch and make it more robust based on comments.
