A bisection reveals that the following patch solves the issue:
8093315a91340bca52549044975d8c7f673b28a1 veth: extend device features

However it relies on:
2681128f0ced8aa4e66f221197e183cc16d244fe veth: reduce stat overhead
For a clean cherry-pick.

And after building and testing the following bug needed to be fixed with:
d0e2c55e7c940a3ee91e9e23a2683b593690f1e9 veth: avoid a NULL deref in veth_stats_one

A test build is available here that solves the issue backported to 3.5/3.8:
