My checkpatch didn't warn about that even with the strict argument
specified.

Note there is just 3 and 6 characters over the preferable limit.
Splitting the lines will make the code less readable (in some extent).

So from that perspective it's ok to exceed 80 characters limit in this
case and not to break the generic kernel coding style convention.
Unless the networking subsystem has a more strict requirement in this
matter.
