In the past, 802.15.4 interfaces and 6LoWPAN interfaces used the
same dev->type (ARPHRD_IEEE802154), and 802.15.4 interfaces were
distinguished from 6LoWPAN interfaces by their differing dev->mtu.
6LoWPAN interfaces have their own ARPHRD type now, so there is no
longer any need to check dev->mtu to distinguish 802.15.4 devices
from 6LoWPAN devices.

The proper return code for trying to send a packet that exceeds the
outgoing interface's MTU is EMSGSIZE, not EINVAL, so patch ieee802154's
raw_sendmsg() to do the right thing. (Its dgram_sendmsg() was already
returning EMSGSIZE for this case.)

->ndo_do_ioctl() can be entered with the rtnl lock already held,
for example when sending a wext ioctl to a device (in which case
the rtnl lock is taken by wext_ioctl_dispatch()), but
mac802154_wpan_ioctl() currently unconditionally takes the rtnl
lock on entry, which can cause deadlocks.
To fix this, bail out of mac802154_wpan_ioctl() before taking the
rtnl lock if the ioctl cmd is not one of the cmds we implement.

Realtek btusb devices don't currently work after suspend/resume because
the updated firmware is quietly lost - the USB hub doesn't notice any
status change upon resume, but some kind of reset has definitely
happened as the LMP subversion has reverted to its original value.
Set the reset_resume flag to trigger probe and upload the new firmware
again.
Like the vendor code, I assume this is not needed when the device is
selected as a wakeup source and hence will retain power during suspend.
On the 2 products I have to hand, when trying this configuration the
hardware seems unable to keep the device powered up during suspend.
The USB hub then detects a status change on resume and does a reset,
so we do not end up in broken state.

This patch removes the mib lock. The new locking mechanism is to protect
the mib values with the rtnl lock. Note that this isn't always necessary
if we have an interface up the most mib values are readonly (e.g.
address settings). With this behaviour we can remove locking in
hotpath like frame parsing completely. It depends on context if we need
to hold the rtnl lock or not, this makes the callbacks of
ieee802154_mlme_ops unnecessary because these callbacks hols always the
locks.

This patch introduce a flag property for the wpan phy structure.
The current flag settings in ieee802154_hw are accessable in mac802154
layer only which is okay for flags which indicates MAC handling which
are done by phy. For real PHY layer settings like cca mode, transmit
power, cca energy detection level.
The difference between these flags are that the MAC handling flags are
only handled in mac802154/HardMac layer e.g. on an interface up. The phy
settings are direct netlink calls from nl802154 into the driver layer
and the nl802154 need to have a chance to check if the driver supports
this handling before sending to the next layer.
We also check now on PHY flags while dumping and setting pib attributes.
In comparing with MIB attributes the 802.15.4 gives us an default value
which we assume when a transceiver implement less functionality. In case
of MIB settings the nl802154 layer doesn't need to check on the
ieee802154_hw flags then.
