[dpdk-dev] [PATCH v3 0/4] Offload flags fixes

[David Marchand]

The important part is the last patch on vhost handling of offloading
requests coming from a virtio guest interface.

The rest are small fixes that I accumulated while reviewing the mbuf
offload flags.

On this last patch, it has the potential of breaking existing
applications using the vhost library (OVS being impacted).
I did not mark it for backport.

Changes since v2:
- kept behavior untouched (to avoid breaking ABI) and introduced a new
  flag to select the new behavior,

Changes since v1:
- dropped patch on net/tap,
- added missing bits in example/vhost,
- relaxed checks on VIRTIO_NET_HDR_GSO_ECN and VIRTIO_NET_HDR_GSO_UDP,
