From 5188cd44c55db3e92cd9e77a40b5baa7ed4340f7 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 30 Oct 2014 18:27:17 +0000 Subject: drivers/net, ipv6: Select IPv6 fragment idents for virtio UFO packets UFO is now disabled on all drivers that work with virtio net headers, but userland may try to send UFO/IPv6 packets anyway. Instead of sending with ID=0, we should select identifiers on their behalf (as we used to).
