Upgrade to 23.01 WAN speed halved
-
Following this thread, I see that the solution is to add (adjust) the following tunable:
hw.cxgbe.niccaps_allowed="1"Is this adjustment recommended for anyone using Chelsio cards regardless of the make and model of the card? I am using a Chelsio T540-SO-CR and have not had any issues with speed. However, I see that that
hw.cxgbe.niccaps_allowedtunable is set to97- is it recommended that I switch the97to1, or only if impacted by this issue?Thanks in advance.

The SO variant didn't appear to be impacted, so no need to add/create loader conf file. It should be set to 1. It was showing 97 as qoute was incorrect in conf file.

For my T540-SO-CR card,
hw.cxgbe.niccaps_allowed="97"as well upon checking its value earlier. I have not made any changes to that tunable setting, this is the default value. Should this be changed to "1" regardless of Chelsio make and model or only on the non SO variants? What does this tunable represent in terms of capabilities on the card? Does setting it to "1" just disable rate limiting? Thanks again. -

@tman222 The doc page has it listed under "Chelsio cxgbe(4) Cards."
"To disable this rate limiting capability, add the following as a Loader Tunable." If you're not affected I guess it doesn't matter for you...?Right - I was curious though whether this change to the tunable should be applied regardless of Chelsio card make and model or just if a regular (non SO) card is being used. The documentation wasn't clear on that.
Thanks again.

Yup AFAIK it only affected that one card.
