Hm, rethinking... This message does not look much different from what NMLinuxPlatform sends when requesting one link [1] or all links [2]. [1] https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/platform/nm-linux-platform.c#n3524 [2] https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/platform/nm-linux-platform.c#n3561 NMLinuxPlatform already has a netlink socket open, it sends very similar get-requests, does parsing of the RTM_NEWLINK and caches the result in a NMPObjectLink instance. I think we should extend platform instead to If you need to poll, you can call nm_platform_link_refresh(). Thomas
