Restore the original regulatory testing functionality and also
make it more flexible by allowing the parameters to be specified
when creating a dynamic radio.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
Add new commands to the hwsim generic netlink family to allow
creating and destroying radios on the fly. The number of channels
a radio supports can be specified when it's created, if it isn't
the module parameter will be used as default.
This should be extended in the future to allow other parameters
to be specified, e.g.
* list of channels
* interface combinations, particularly P2P_DEVICE support
* regtest
* and pretty much all other hardware capabilities

Reject wmediumd registrations when any devices have multi-channel
capability, but register the generic netlink family unconditionally
to make it possible to add new commands that shouldn't depend on
the number of (default) channels.

Accessing the current channel definition in mac80211
when processing RX packets is problematic because it
could have been updated when a scan is issued. Since a
channel change involves flushing the existing packets
in the RX queue before a chip-reset is done, they would
be processed using the wrong band/channel information.
To avoid this, use the current channel information
maintained in the driver.

The firmware doesn't support per packet encryption selection, so disable hw
encryption support completely while a monitor interface is present to support
injection of packets (which shouldn't get encrypted by hw).
To enforce the changed hw encryption support force a disassociation on
non-monitor interfaces.
For disassociation a workaround using hw connection monitor is employed,
which temporary enables hw connection manager flag.

With a dissasociated card I often encoutered very long scan delays.
My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.
Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.
