Subject: net/smc: add generic netlink support for system EID
Git-commit: 3c572145c24e21c24e1cd0fd168011eaba85da8e
Patch-mainline: v5.16-rc1
References: jsc#SLE-18331

With SMC-Dv2 users can configure if the static system EID should be used
during CLC handshake, or if only user EIDs are allowed.
Add generic netlink support to enable and disable the system EID, and
to retrieve the system EID and its current enabled state.
