[systemd-devel] Configure netdev RPS using systemd-networkd

[Renjaya Raga Zenta]

Hi,

We want to implement our networking using systemd-networkd. We think
systemd is stable enough right now, so we want to try more "systemd-only"
solution.

In our environment, we use RPS (Receive Packet Steering) for load balancing
and scaling. It's a kernel feature implemented a long time ago. You could
visit the documentation at
https://www.kernel.org/doc/html/latest/networking/scaling.html.

Currently, we manually do this after network interface is configured:

echo f > /sys/class/net/eth0/queues/rx-0/rps_cpus

where f is bitmap mask 1111, it means to utilize 4 cpus.

Will this use case be implemented in systemd-networkd? Or should we use a
third party solution such as networkd-broker or networkd-dispatcher?

Thanks.
