The code already has dozens of long lines already.
This is generally a problem because the variable names are pretty long so strict 80 column adherence generally isn't possible.
A possible way to shorten these relatively long variable name/line lengths is to use a temporary for
pmlmeprv->LinkDetectInfo
struct rt_link_detect *ldi = &pmlmeprv->LinkDetectInfo;
so:
I am agree on this approach but Let's wait for Jes opinion on it.
