Yeah... One problem I see with the Linux project is the lack of
docs/specs. Often we don't know what is right and what is wrong.

Thanks! This way we can make sure LAPB would automatically connect in
all situations.

Since we'll have a netif_carrier_ok check in NETDEV_UP handing, it
might make the code look prettier to also have a netif_carrier_ok
check in NETDEV_GOING_DOWN handing (for symmetry). Just a suggestion.
You can do whatever looks good to you :)

Thanks!
