HI Paolo,

could this patchset be related?
Uh oh, yes it should.  Jason, any ways to fix it?  I suppose we
need to
disable UFO in the newest machine types, but do we also have to do
(software) UFO in vhost-net and QEMU for migration compatibility?
Any news on this?

Since we probe UFO support, it will be disabled automatically on device

For the issue of migration, I think the only way is trying to fix it in
But 4.14 is around the corner and the patchset is already included.
Shouldn't this get fixed before 4.14 is released?
We will try to seek a solution as soon as possible. If we can't catch
4.14, we will do it for stable for sure.
Jason, can you write to netdev and Cc Linus and me?



Paolo, see this https://www.spinics.net/lists/netdev/msg465454.html

Just notice this today since I'm not on the cc list.
