UPD on multinode neutron grenade: it indeed seems like MTU issue (multiple  
rechecks show we pass past the ssh exchange check). We are currently  
working on a bunch of fixes that should get us in better shape for the job:


It also seems like the same fixes may help, if not fix, other multinode  
jobs we have non-voting and failing in neutron gate now. [Need more  
rechecks to be sure.]

Changes already span neutron, devstack, devstack-gate repos. Hence adding  
[devstack] to the thread tags.

Reviews are obviously welcome.
