[PATCH 0/2] virtio-net: Clarify virtio_net_hdr size and rx buffer size

[Parav Pandit <parav@nvidia.com>]

There are few small issues around size of receive buffer and size of the
struct virtio_net_hdr as following.

1. VIRTIO_NET_F_HASH_REPORT is only applicable on the rx side processing.
   However it changes the size of the struct virtio_net_hdr for the tx side
   as well. This was not clarified when VIRTIO_NET_F_HASH_REPORT feature was
   introduced.

2. Receive buffer size calculation description and requirements did not
   reflect negotiation of VIRTIO_NET_F_HASH_REPORT.

3. Receive buffer size calculation was incorrect for ipv6 guest gso feature.

Above issue 2 was reported in [1].
Since issue 2 and 3 both touches the same set of requirements and description,
they are updated under a new issue along with tx side fix as well touching the
clarification needed for VIRTIO_NET_F_HASH_REPORT.

Hence above three issues are fixed under issue of [2].

Patch summary:
patch-1 fixes receive side description and requirement
patch-2 adds transmit side clarification for VIRTIO_NET_F_HASH_REPORT

Fixes: https://github.com/oasis-tcs/virtio-spec/issues/170
Fixes: https://github.com/oasis-tcs/virtio-spec/issues/183

Please review.
