Choose the networking configuration mode according to the current contents of /etc/scylla.d/cpuset.conf. If it doesn't exist - use the default mode. If it exists - use the mode that has been used for generation of the CPU set. Store the configuration into the /etc/scylla.d/perftune.yaml Signed-off-by: Vlad Zolotarov <vladz@scylladb.com>
