RPS and probably other kernel features are currently broken on some if not
all DSA devices. The root cause of this that skb_hash will call the
flow_disector.

Hi John

What is the call path when the flow_disector is called? I'm wondering
if we can defer this, and call it later, after the tag code has
removed the header.

Would not you usually want to configure RPS at the DSA network device
level where the switch tag has already been popped and you are
processing a regular Ethernet frame at that point?
