Cpuset.conf - setup

Upgrade from 5.0 to 5.1
#ScyllaDB version: 5.1
#Cluster size: 3 nodes
os amazon Linux 2023

Hello team, I am following documentation Upgrade Guide - ScyllaDB 5.0 to 5.1 | ScyllaDB Docs and to complete upgrade, it seems I have to change Mode in perftune.yaml.

When I execute command “sudo scylla_sysconfig_setup --nic ens5 --homedir /scylla --confdir /scylla/config” file /etc/scylla.d/cpuset.conf is generated. After that I restart scylla service and /etc/scylla.d/perftune.yaml is generated.

cat /etc/scylla.d/cpuset.conf
CPUSET="--cpuset 0-1 "

cat /etc/scylla.d/perftune.yaml
cpu_mask: '0x00000003'
mode: mq
nic:
- ens5
tune:
- net

it suppose to be mode sq_split but instead it is mq. wonder if there is something wrong with command and/or current config?

btw, cluster is up and running but trying to complete scylladb documentation and tune best as possible ec2 instance type i4g.large.

Thank you
