====================
pull-request: ieee802154-next 2018-08-06

An update from ieee802154 for *net-next*

Romuald added a socket option to get the LQI value of the received datagram.
Alexander added a new hardware simulation driver modelled after hwsim of the
wireless people. It allows runtime configuration for new nodes and edges over a
netlink interface (a config utlity is making its way into wpan-tools).
We also have three fixes in here. One from Colin which is more of a cleanup and
two from Alex fixing tailroom and single frame space problems.
I would normally put the last two into my fixes tree, but given we are already
in -rc8 I simply put them here and added a cc: stable to them.
