Add a new HWSIM_ATTR_USE_CHANCTX attribute to the HWSIM_CMD_CREATE_RADIO command to allow the creation of radios with one channel that use channel contexts. If this attribute is not present, the behaviour is the same as before (ie. single channel radios don't use channel contexts and multi channel radios do).

|
|
*
|
|
* Frame transmission and registration support exists to allow userspace
|
|
* entities such as wmediumd to receive and process all broadcasted
|
|
* frames from a mac80211_hwsim radio device.
|
|
*
|
|
* This allow user space applications to decide if the frame should be
|
|
* dropped or not and implement a wireless medium simulator at user space.
|
|
*
|
|
* Registration is done by sending a register message to the driver and
|
|
* will be automatically unregistered if the user application doesn't
|
|
* responds to sent frames.
|
|
* Once registered the user application has to take responsibility of
|
|
* broadcasting the frames to all listening mac80211_hwsim radio
|
|
* interfaces.
|
|
*
|
|
* For more technical details, see the corresponding command descriptions
|
|
* below.
