We are running the external interfaces in LXC containers
i.e. in a netns and depend on that no defragmentation is done in this stage.
Fragments can arrive on any interface on any blade so...
I had an idea of a sysctl to be able to turn off nf_defrag_ipv{4,6} per namespace
Default is of course on so excisting apps will be happy.
Any objections to that idea ?
