similar to: [GIT PULL] first round of vhost-net enhancements for net-next

David, This is an amended pull request: I have rebased the tree to the correct patches. This has been through basic tests and seems to work fine here. The following tree includes a couple of enhancements that help vhost-net. Please pull them for net-next. Another set of patches is under debugging/testing and I hope to get them ready in time for 2.6.35, so there may be another pull request later.

The VNET_LE flag was introduced to fix accesses to virtio 1.0 headers that are always little-endian. It can also be used to handle the special case of a legacy little-endian device implemented by a big-endian host. Let's add a flag and ioctls for big-endian devices as well. If both flags are set, little-endian wins. Since this is isn't a common usecase, the feature is controlled by a

Since we now have support for software CRC32c offload, turn it on for macvlan and macvtap devices so that guests can take advantage of offload SCTP checksums to the host or host hardware.
