Seems like only patch 1, 2 and 5 in this [1] series are selected?  We
also need patch 4, upstream commit 6f2684bf2b44 ("veth: Use tstats
per-CPU traffic counters").  Otherwise the fix won't work, and the code
will be wrong [2] .

We should've included a "Depends on patch..." note for stable in the
commit message.

Thanks,

[2] veth still uses @lstats, but patch 5 makes skb_do_redirect() update
    it as @tstats.
