Since "wireless-regdb: remove antenna gain" was merged in the
wireless-regdb tree, the awk script parser has been incompatible
with the 'official' regulatory database. This fixes that up.
Without this change the max EIRP is set to 0 making 802.11 devices
useless.
The fragile nature of the awk parser must be replaced, but ideas
over how to do that in the most scalable way are being reviewed.
In the meantime update the documentation for CFG80211_INTERNAL_REGDB
so folks are aware of expectations for now.

Some VHT TDLS peers (Google Nexus 5) include the VHT-AID IE in their
TDLS setup request/response. Usermode passes this aid as the station
aid, causing it to fail verifiction, since this happens in the
"set_station" stage. Make an exception for the TDLS use-case.

Driver is now responsible for veryfing if the
switch is possible.
Since this is inherently tricky driver may decide
to disconnect an interface later with
cfg80211_stop_iface().
This doesn't mean driver can accept everything. It
should do it's best to verify requests and reject
them as soon as possible.

MAX_JIFFY_OFFSET has no meaning when calculating the

Currently, cfg80211 tries to implement ethtool, but that doesn't
really scale well, with all the different operations. Make the
lower-level driver responsible for it, which currently only has
an effect on mac80211. It will similarly not scale well at that
level though, since mac80211 also has many drivers.
To cleanly implement this in mac80211, introduce a new file and
move some code to appropriate places.

We're currently sending NEW_WIPHY events for renames (which
is a bit odd, but now can't be changed), but also send them
for really new devices that register.
Also send DEL_WIPHY events when a device is removed, the
event ID for this was already reserved.

Channels in 2.4GHz band overlap, this means that if we
send a probe request on channel 1 and then move to channel
2, we will hear the probe response on channel 2. In this
case, the RSSI will be lower than if we had heard it on
the channel on which it was sent (1 in this case).
The firmware / low level driver can parse the channel in
the DS IE or HT IE and compensate the RSSI so that it will
still have a valid value even if we heard the frame on an
adjacent channel. This can be done up to a certain offset.
Add this offset as a configuration for the low level driver.
A low level driver that can compensate the low RSSI in this
case should assign the maximal offset for which the RSSI
value is still valid.

Users may need information about the expected throughput
towards a given peer.
This value is supposed to consider the size overhead
generated by the 802.11 header.
This value is exported in kbps through the get_station() API
by including it into the station_info object.
Moreover, it is sent to user space when replying to the
nl80211 GET_STATION command.
This information will be useful to the batman-adv module
which will use it for its new metric computation.

This also propagates through the drivers.
The orinoco driver uses the cfg80211 API structs for internal
bookkeeping, and so needs a (void *) cast that removes the
const - but that's OK because it allocates those pointers.

Change the type of NL80211_ATTR_CSA_C_OFF_BEACON and
NL80211_ATTR_CSA_C_OFF_PRESP to be NLA_BINARY which allows
userspace to use beacons and probe responses with
multiple CSA counters.
This isn't breaking the API since userspace can
continue to use nla_put_u16 for this attributes, which
is equivalent to a single element u16 array.
In addition advertise max number of supported CSA counters.
This is needed when using CSA and eCSA IEs together.

There is no need to pass NL80211_IFTYPE_UNSPECIFIED when calling
cfg80211_chandef_dfs_required() since we always already have the
interface type. So, pass the actual interface type instead.
Additionally, have cfg80211_chandef_dfs_required() WARN if the passed
interface type is NL80211_IFTYPE_UNSPECIFIED, so we can detect
problems more easily.
