Thanks.  I bisected it to commit
ae0e8e82205c903978a79ebf5e31c670b61fa5b4 : "veth: prevent oops caused by
netdev destructor".  That moves the free_percpu(priv->stats) from
veth_dev_free to veth_close().  Since it gets allocated at
veth_dev_init, and dveth_xmit uses it unconditionally, that seems like a
likely cause of the oops?
