So, if we have multiqueue, we do everything needed to get RSS
flowid/type. That means, with num_queues > 1 we can just expose those.

Yeah, I think the right thing to do is:
* If the descriptor says it's RSS, then use the flowid + rss type
* else, set it to queue id and set the type to opaque.

No, you're absolutely right. However, you (a) get flowid for L3/L4
V4/v6 but not other things, and (b) I was worried about changing the
default behaviour of the driver, and who knows what other weird crap
people may have done to their local driver. stuff like enabled
checksums instead, or hacked in

I care about igb(4) right now and I350 specifically. I checked the spec
and section 7.
So, the 32 bit field that has the flowid in the rx descriptor can mean
multiple things - not just the flowid.
For igb it can also mean one of the RX checksums.
for ixgbe it can also mean RX checksum, or flowdirector flow
information, or a few other thngs.

It'd break things if not all igb chips behave the same way in t
Hi,
The main reason I didn't add it outside of RSS is that I didn't want
to impact the behaviour that was there before. Before, it wasn't using
the flowid - only the msix/queue id.
I read the intel datasheets about that particular field - I'm pretty
sure that by default we'll only see RSS hashed

I believe this was added by Adrian as part of RSS work and was not there
before. I may be wrong.
