Matthew,
I don't use any special tricks to make symmetric RSS work. Furthermore, it
works not only with 0x6d5a.

Vladimir

That's really encouraging. Thanks!
One thing I'll note is that if my reading of the original paper is
accurate, the 0x6d5a value isn't there in order to cause symmetry - other
repeated 16 bit values will do that, as you've seen. What the 0x6d5a value
gets you is symmetry while preserving RSS's e

Vladimir,
All of this is super-awesome code. I agree having SW RSS would be quite nice.

Hi Matthew,
I just verify RSS symmetric in my code, all works great. I have 82599 NIC
and dpdk 1.7.0. Moreover, we can use not only 0x6d5a, but repeated random 2
bytes for 4 tuple, and repeated 4 bytes for 2 tuple in rss hash key. Bellow
some code:
uint8_t my_rss_key[40];
static const struct rte_e

No, AFAIK.
Submitting a patch would be a good start I think.

Hi Thomas,

Hey Folks,
I have essentially the same question as Matthew. Has there been progress
in this area?

A few months ago we had this thread about symmetric hashing of TCP in RSS:
http://dpdk.org/ml/archives/dev/2014-December/010148.html
I was wondering if we ever did figure out how to get the 0x6d5a hash key
mentioned in there to work, or another alternative one.
Thanks,
Matthew.
