...f the packet gets encapsulated e.g. by etherip etc? Is Linux smart enough to be able to put the extra headers on in-place if there is enough head room? If so, the current situation is positively better.

...compile if IOMMU is enabled in the kernel config. Warning, dom0 will crash during boot of the kernel if IOMMU is enabled. These changes do not affect non-IOMMU enabled kernels (a fact I have verified myself). I am currently working on debugging the IOMMU dom0 crash.

While working bug #143, it came to my attention that no verbose error is loged if the dom0 kernel mangles a packet and tries to checksum offload it. This should let the user know what is going wrong (instead of silently dropping the packet).

I encountered a problem with dom0 when rebooting and running an intel gigabit card using the pro/1000 driver.

I am trying to dedicate a number of PCI ports to DomU and no success! The PCI devices I am trying to dedicate are QLogic 23xx cards! I am using SUSE 10.1 with latest xen-unstable! I have followed all the instructions given in latest xen 3.0 manual. Like building the backend support in Dom0 Building the frontend support in DomU Using the pciback.hide=(xx:xx.x) in Dom0 command

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
