I'm not sure about this. All the other RTM_GETxxx are such that RTM_GETxxx % 4 == 2. Following the current pattern, 124 should be reserved for RTM_NEWxxx, and RTM_GETEECSTATE would be 126.
More importantly, why is this added to rtnetlink (routing sockets)? It appears to be unrelated?
Looks like this should be in ethtool (it has netlink api nowadays) or devlink.
We identified it as a generic place in previous RFCs. Ethtool calls are not available in non-ethernet packet networks and the concept of that functionality is - any packet network can implement it - SONET, GPON or even wireless.
