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.
Also, why are you leaving a gap (which you end up filling in patch 4/6)?

Why stuff this in a struct instead of using an attribute?
