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?
Hi Florian,
is explained in my mail to Andrew, you really want to be able to setup
RPS for all devices in the chain to free up the core handling IRQs
