I think this is still on topic!

Sorry, wasn't too clear on that.

What I meant is that _existing_ "egress redirect" already gets us into
crazy loops - the veth misconfig being just one example of, but
many more exist (many device stacking constructs, with lower dev issuing
an egress-redirect back to the topmost dev).

Point is, IMO loop detection (whether/how addressed), is orthogonal to
this series implementing "ingress redirect", and doesn't seem as a
strict prerequisite to adding the "ingress redirect" functionality to
act_mirred.

We can later address any loop-detection improvements in mirred.
WDYT?

Thanks,
Shmulik
