[PATCH v4 0/2] virtio-net: support distinguishing between partial and full checksum

[Heng Qi <hengqi@linux.alibaba.com>]

If VIRTIO_NET_F_GUEST_CSUM is negotiated, the driver does not support the
loading of XDP because it can receive packets with partial checksum.

This prevents users using XDP from enjoying the benefits of device
calculation and validation of checksum.

This patch set is designed to resolve this issue.

Changelog:
=========
v3->v4:
- Patch[1/2]: Update the description for VIRTIO_NET_F_GUEST_CSUM.
- Patch[2/2]:
  - Streamline some repetitive descriptions.
  - Add how features should work, when to be enabled, and overhead.

v2->v3:
- Add a section named "Driver Handles Fully Checksummed Packets"
  and more descriptions. @Michael

v1->v2:
- Modify full checksum functionality as a configurable offload
  that is initially turned off. @Jason
