Subject: ETH_RSS_IP only does not seem to balance traffic
Date: Thu, 13 Jan 2022 00:52:04 +0900 (JST)	[thread overview]
Message-ID: <20220113.005204.1354235040127303916.yasu@nttv6.jp> (raw)


Hi,

My system developper friend recently ran into a problem where
l3fwd does not appear to receive balanced traffic on Intel XL710,
but it is resolved when the attached patch is applied.

-            .rss_hf = ETH_RSS_IP,
+            .rss_hf = ETH_RSS_IP | ETH_RSS_TCP | ETH_RSS_UDP,

IIRC I ran into a similar problem 3 or 4 years back,
but didn't report then because I believed I was doing something silly.
But since my friend is an experienced engineer, I feel like
it may be better (for the community) to ask this in the list.

We are using dpdk-stable-18.11.6 and igb_uio.

What are we doing wrong?

If it is not a FAQ, I can test it again with more recent stable,
and will report the details.

Thanks.

Best,
Yasu
