[PATCH 1/4] virtio_net: Fix skb->csum_start computation
From: Mark McLoughlin <markmc at redhat.com>
hdr->csum_start is the offset from the start of the ethernet
header to the transport layer checksum field. skb->csum_start
is the offset from skb->head.
skb_partial_csum_set() assumes that skb->data points to the
ethernet header - i.e. it computes skb->csum_start by adding
the headroom to hdr->csum_start.

[PATCH 1/3] skb_partial_csum_set
Implement skb_partial_csum_set, for setting partial csums on untrusted packets.
Use it in virtio_net (replacing buggy version there), it's also going
to be used by TAP for partial csum support.

[PATCH 0/6] virtio_net: use common code for virtio_net_hdr and skb GSO conversion
Hi,
This patches introduce virtio_net_hdr_{from,to}_skb functions for
conversion of GSO information between skb and virtio_net_hdr.
Mike Rapoport (6):
virtio_net: add _UAPI prefix to virtio_net header guards
virtio_net: introduce virtio_net_hdr_{from,to}_skb
macvtap: use common code for virtio_net_hdr and skb GSO conversion
tuntap: use common code for virtio_net_hdr and skb GSO

[PATCH] virtio_net: introduce VIRTIO_NET_HDR_F_DATA_VALID
There's no need for the guest to validate the checksum if it have been
validated by host nics. So this patch introduces a new flag -
VIRTIO_NET_HDR_F_DATA_VALID which is used to bypass the checksum
examing in guest. The backend (tap/macvtap) may set this flag when
met skbs with CHECKSUM_UNNECESSARY to save cpu utilization.
No feature negotiation is needed as old driver just ignore this flag.

I compressed the whitespace to avoid going over 80 cols. A choice of lesser
evils :)

[PATCH 1/3] Cleanup and simplify virtnet header
1) Turn GSO on virtio net into an all-or-nothing (keep checksumming
separate). Having multiple bits is a pain: if you can't support something
you should handle it in software, which is still a performance win.
2) Make VIRTIO_NET_HDR_GSO_ECN a flag in the header, so it can apply to
IPv6 or v4.
3) Rename VIRTIO_NET_F_NO_CSUM to VIRTIO_NET_F_CSUM (ie. means we do
checksumming).

[PATCH] virtio_net.c gso & feature support
Feedback welcome, as always!
(There's been talk of a virtualization git tree, in which case there'll
be a decent home for these patches soon).
Cheers,
Rusty.
==
Add feature and GSO support to virtio net driver.
If you don't do GSO, you can simply ignore the first sg element of
every outgoing packet, and tack a dummy one on every incoming.
