This --- is still indented.

On top of that please tag the patch for the tree to which networking
maintainers apply fixes (by specifying [PATCH net v5] instead just
[PATCH v5] in the subject).

And add a Fixes tag. If the bug dates all the way back to the start of
the git era add:

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

otherwise use the commit which added the buggy code.
