BUG: ice: E830 fails RSS table adjustment with ethtool -X

BUG: ice: E830 fails RSS table adjustment with ethtool -X

https://bugzilla.kernel.org/show_bug.cgi?id=220839

Kernel: stable-6.12.58
NIC: E830 100G dual port

When trying to adjust RSS table # of queues on E830 with

ethtool -X eth0 equal 8

we see this error in logs

    [ 6112.110022] [ T303140] ice 0000:c1:00.1: Failed to configure RSS 
hash for VSI 8, error -5
     [ 6112.528002] [ T303170] ice 0000:c1:00.0: Failed to configure RSS 
hash for VSI 6, error -5

This command works fine on E810 nics with the same driver.

Firmware/package, and NVM version info attached to bugzilla.

We're already trying this on 6.18 but data not available yet, however 
it's still a bug.

Hi Jesse,

A fix for this issue is in review on IWL, "[PATCH net] ice: fix setting
RSS VSI hash for E830"
https://lore.kernel.org/intel-wired-lan/979e42ca-66fb-4ca6-b68f-c10b4e441369@linux.dev/T/#mf07d85c072f472f8add658f2cbeba8de79ba31b9
