Important differences:
- if_multiaddrs is a LIST, not a TAILQ
- locking is done using splimp / splx, not mutexes
- ALTQ macros are currently only half-working, this will change in the next
  days
- some additional changes for ALTQified drivers are needed
- vlan is handled differently
- m_devget has a different semantic

That's what I remember off-memory. If you want details or help, just ask.
