[PATCH v5 bpf-next 4/6] virtio-net: support IFF_TX_SKB_NO_LINEAR

From: Alexander Lobakin <hidden>
Date: 2021-02-16 14:38:11
Also in: bpf, lkml
Subsystem: networking drivers, the rest, virtio net driver · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds, "Michael S. Tsirkin", Jason Wang

From: Xuan Zhuo <xuanzhuo@linux.alibaba.com>

Virtio net supports the case where the skb linear space is empty, so add
priv_flags.
