Yes, this doesn't work like a typical egress redirect, but is aimed at
forwarding the matched packets to a different queue-group/traffic class
on the same device, so some sort-of ingress redirect in the hardware. I
possibly may not need the mirred-redirect as you say, I'll look into the
g_act way of doing this with a new gact tc action.
