Subject: [PATCH net-next v2 2/3] virtio-net: support IFF_TX_SKB_NO_LINEAR
Date: Wed, 20 Jan 2021 15:49:10 +0800 [thread overview]
Message-ID: <d54438cec1fc86a1cb0166098493b1aa6a15885a.1611128806.git.xuanzhuo@linux.alibaba.com> (raw)
In-Reply-To: <20210119142726.4970-1-alobakin@pm.me>
In-Reply-To: <cover.1611128806.git.xuanzhuo@linux.alibaba.com>
Virtio net supports the case where the skb linear space is empty, so add
priv_flags.
