Simon reported that ndo_change_mtu() methods were never
updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted
in commit 501a90c945 ("inet: protect against too small
mtu values.")
We read dev->mtu without holding RTNL in many places,
with READ_ONCE() annotations.
It is time to take care of ndo_change_mtu() methods
to use corresponding WRITE_ONCE()

Similar with commit 08d323234d ("net: fou: rename the source for linking"),
We'll need to link two objects together to form the team module.
This means the source can't be called team, the build system expects
team.o to be the combined object.
