Another checksum offload problem was reported on xen-users, when using a domU as a firewall: http://lists.xensource.com/archives/html/xen-users/2006-04/msg01150.html It also fails without VLANs. The path from dom0->domU with ip_summed==CHECKSUM_HW/proto_csum_blank==1 is broken. - skb_checksum_setup() assumes that a checksum will definitely be calculated in dev_queue_xmit(), but the

Not tested in any way. The original code for offload setting seems broken as it resets the features on every netback reconnect. This will set GSO_ROBUST at device creation time (earlier than connect time). RX checksum offload is forced on - so advertise as it is. Signed-off-by: Micha?

UFO support in the kernel applies to both IPv4 and IPv6 protocols with the same device feature. However some devices may not be able to support one of the offloads. For this we split the UFO offload feature into 2 pieces. NETIF_F_UFO now controlls the IPv4 part and this series introduces NETIF_F_UFO6. As a result of this work, we can now re-enable NETIF_F_UFO on virtio_net devices and restore

Now that we have SCTP offload capabilities in the kernel, we can add them to virtio as well. First step is SCTP checksum. We need a new freature in virtio to negotiate this support since SCTP is excluded with the stardard checksum and requires a little bit extra. This series proposes VIRTIO_NET_F_SCTP_CSUM feature bit. As the "little bit extra", the kernel uses a new bit in the skb

Hi Keir: [NET] front: Fix features on resume when csum is off When the netfront driver is resumed the features are renegotiated with the backend. However, I forgot take into account the status of the TX checksum setting. When TX checksum is disabled by the user, we cannot enable SG or TSO since both require checksum offload. This patch makes xennet check the checksum setting before
