====================
l2tp: miscellaneous cleanups
This series of patches makes the following cleanups and improvements to
the l2tp code:
* various API tweaks to remove unused parameters from function calls
* lightly refactor the l2tp transmission path to capture more error
conditions in the data plane statistics
* repurpose the "magic feather" validation in l2tp to check for
sk_user_data (ab)use as opposed to refcount debugging
* remove some duplicated code
