Antonio Quartulli says:

====================
Included changes:
- code restyling and beautification
- use int kernel types instead of C99
- update kereldoc
- prevent potential hlist double deletion of VLAN objects
- fix gw bandwidth calculation
- convert list to hlist when needed
- add lockdep_asserts calls in function with lock requirements
  described in kerneldoc
