Am I right? That would indeed be a problem. This happened once already: http://www.spinics.net/lists/kvm/msg110142.html That time, the offending commit was reverted (after the primary issue with IPv6 fragments it aimed to work around was fixed properly). In any case, this is something that needs to be discussed in upstream even if the timing is really unfortunate (4.14 final around the corner and netconf/netdev conference this week). -- You are receiving this mail because: You are on the CC list for the bug.
