The extra boolean is because we want to only fail particular subcases. I think that's legit. If the other cases regress we want to know. Otherwise running the test on SW bridge is only useful for catching crashes (so less useful).
So we probably need to reset FAIL_TO_XFAIL in this case. Any preference on how to go about that? I'm tempted to:

Likewise you only annotate with xfail_on_* the testcases that you want to xfail. The FAIL_TO_XFAIL ought to only be set for that one subcase and then revert to its former value. (That's the intention anyway.)
So we probably need to reset FAIL_TO_XFAIL in this case. Any preference on how to go about that? I'm tempted to:

I don't follow. The test has two legs, one creates a VRF and attaches p2, the other creates a bridge and attaches p2. Whether p1 and p2 are veth or HW seems orthogonal to whether $rcv_if_name is a bridge or a veth.

Right, my superficial understanding was that the main distinction is whether p2/h2 can do the filtering (or possibly some offload happens). So if p1,p2 are veths we know to XFAIL, doesn't matter if we're in the vrf or bridge configuration, cause these construct will not filter either.
If I'm not making sense - I'm probably confused, I can code up what you suggested, it will work, just more LoC :)

I'm not sure myself, but from the commit message it looks like the issue is with $rcv_if_name being the bridge.
But the patch that you inline is R-b'd and T-b'd by Vladimir, so I'm going to assume it's doing the right thing.

If xfail_on_veth $h1 is all that's needed, then I really don't see a reason why not just do this:
