Minor nit:

I think both comments needs to be a bit more clear. I.e. tc_at_ingress
tells the *current* location whether we are invoked from ingress or
egress. And, tc_from_ingress explains the *previous* location, whether
the skbs has been mirred from ingress path or egress path.

Otherwise, the rest looks good to me.
