This looks good for 4.19 and 5.1, so I'll push out new stable kernels in
a bit for them.

But for 4.14 and older, we don't have the "hint" to know this is an
outbound going packet and not to apply these checks at that point in
time, so this patch doesn't work.

I'll see if I can figure anything else later this afternoon for those
kernels...
