Hi. I'm pushing devlink support to systemd, have the systemd-devlinkd testsuite based on netdevsim module. That is not currently distributed in Debian kernel package. The systemd maintainers exposed desire to be able to run the systemd-devlinkd test as part of CI which include tests on Debian systems. Would it be possible for youto add the module please? It should be as easy as just adding "CONFIG_NETDEVSIM=m" config option. Thanks!
