802.15.4 frames by the Linux kernel and the RAW sockets can see

I hope I did it right, not sure if I really need rcu functionality in these

Hey netdev community,
I am trying to solve some issue which Eric Dumazet points to me by
commit ca0edb131bdf ("ieee802154: 6lowpan: fix possible NULL deref in
lowpan_device_event()").
The issue is that dev->type can be changed during runtime. We don't have
any problems with the netdevice notifier

Hi netdev community,
I am again on bug fixing in 6lowpan branch and thought that my
needed_headroom and needed_tailroom of net_device are available inside
my ndo_start_xmit() callback.
In case of a UDP socket, it was not the case. I send a fix now to use
