[PATCH 1/3] tun: Interface to query tun/tap features.
The problem with introducing checksum offload and gso to tun is they need to set dev->features to enable GSO and/or checksumming, which is supposed to be done before register_netdevice(), ie. as part of TUNSETIFF. Unfortunately, TUNSETIFF has always just ignored flags it doesn't understand, so there's no good way of detecting whether the kernel supports new IFF_ flags. This patch

[PATCH v2 net 0/2] drivers/net,ipv6: Fix IPv6 fragment ID selection for virtio
The virtio net protocol supports UFO but does not provide for passing a fragment ID for fragmentation of IPv6 packets. We used to generate a fragment ID wherever such a packet was fragmented, but currently we always use ID=0! v2: Add blank lines after declarations Ben.
