I think that device supports only a specific RSS key length. We'll try a programmatic solution, but meanwhile can you change https://github.com/stanford-esrg/retina/blob/47f2721e6b59a2e6ae2c4f584d3f3013ddd6468d/core/src/port/mod.rs to set rss_key_len to 52 and expand the key so it is long enough?

[hassaan-ali-arista]

I tried it but getting the same error after changing the rss_key_len to 52 and expanding the key.

Did you change the rss_hf to the expected value?

[hassaan-ali-arista]

Just to confirm, I need to change the following value to what exactly?

port_conf.rx_adv_conf.rss_conf.rss_hf =
(dpdk::ETH_RSS_IP | dpdk::ETH_RSS_TCP | dpdk::ETH_RSS_UDP) as u64;

[thegwan]

Try 0x7ef8, the valid value indicated in the error message.

[hassaan-ali-arista]

Yes, I changed it to 0x7ef8. I get the following errors:

The number of descriptors indicated in the config (32768) is too high for your setup, I suggest changing it to within the suggested range. You'll probably also need to adjust the number of queues depending on support from the NIC (this can all be modified in the config file).
