Kernel crash when using ICE driver and trying to use anything other than 2048 RX descriptors

[an0sv]

Setting the RX descriptor using ethtool -G to any other value than 2048 crashes the kernel (CentOS 7.9) .

I'am using the latest master netmap (today). I had th esame issue with i40e with an earlier netmap release but with master
that worked which is great but the problem still exists with ICE

Anyone that has the same issue annd/or knows of a work around?

I am not able to reproduce this. What is the version of the ice driver?

Just to be precise.

I can set the rings to 8196 using ethtool so that works fine.

The problem is that the kernel crashes when I starting my application when it opens the netmap dev

A question, what kernel version, ice version and netmap version are you using? I would like to test with the exact same to see if it works for me as-well
