Re: [PATCH net-next v4 2/5] net/lapb: support netdev events

[Xie He]

Should we also handle the NETDEV_UP event here? In previous versions
of this patch series you seemed to want to establish the L2 connection
on device-up. But in this patch, you didn't handle NETDEV_UP.

Maybe on device-up, we need to check if the carrier is up, and if it
is, we do the same thing as we do on carrier-up.
