The compiler does a better job at deciding what to inline than we
humans do. If you can show the compiler is doing it wrong, then we
might accept them. But in general, netdev does not like inline in .C
file. Also, nothing in MDIO is hot path, it spends a lot of time
waiting for a slow bus. So inline is likely to just bloat the code for
no gain.
