If simulation needs predictable permanent mac addresses of hwsim wireless phy, this patch add the ability to create a new radio with a user defined permanent mac address. Allowed mac addresses needs to be locally administrated mac addresses (as also the former fixed 42:* and 02:* were). To do not break the operation with legacy software using hwsim, the new address is set twice. The problem here is, the netlink call backs use wiphy->addresses[1] as identification of a radio and not the proposed permanent address (wiphy->addresses[0]). This design decision is not documented in the kernel repo, therefore this patch simply reproduces this, but with the same address.

|
|
* 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.
|
|
*
|
|

|
|
* 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
