Note that if I do the same on 3.10.327-el7.x86_64 (RHEL7u2) the problem
does not occur.  I have not yet tested on older mainline kernels, but plan
to do so shortly.  Also note that in both cases, the link partner is running
3.10.327-el7.x86_64. ]

I've now bisected this to 272d96a5ab10 "net: vxlan: lwt: Use source ip address
 during route lookup."  Which is interesting, because I'm using a vxlan
 netdevice, not an LWT; maybe in the former case the saddr is bogus.
Presumably the route lookup gets cached and that's why it remembers the broken
 state.
