Hello, After a few exchanges about inter-PAN management with Alexander, it was decided that most of this series would be dropped, because the kernel should in the end not really care about keeping a local copy of the discovered coordinators, this is userspace job. So here is a "first" version of the scanning series which hopefully meets the main requirements discussed the past days on the mailing list. I know it is rather big, but there are a few very trivial patches there, so here is how it is built: * net: mac802154: Allow the creation of coordinator interfaces Beaconing must be reserved to coordinator interfaces, so we must support the creation of these interfaces in the mac layer. * net: ieee802154: Advertize coordinators discovery * net: ieee802154: Handle coordinators discovery Introduction of a user interface and then a cfg802154 interface for coordinators discovery and advertisement. * net: ieee802154: Define frame types * net: ieee802154: Add support for user scanning requests * net: ieee802154: Define a beacon frame header * net: mac802154: Prepare forcing specific symbol duration * net: mac802154: Introduce a global device lock * net: mac802154: Handle passive scanning User requests to scan and MAC handling of these requests. * net: ieee802154: Add support for user beaconing requests * net: mac802154: Handle basic beaconing User requests to send beacons and MAC handling of these requests. * net: ieee802154: Add support for user active scan requests * net: mac802154: Handle active scanning User requests to scan actively and MAC handling of these requests. * net: ieee802154: Add support for allowing to answer BEACON_REQ * net: mac802154: Handle received BEACON_REQ User requests to answer BEACON_RQ and MAC handling of these requests. * net: ieee802154: Handle limited devices with only datagram support * ieee802154: ca8210: Flag the driver as being limited This is a result of a previous review from Alexander, which pointed that the hardMAC ca8210 would not support the scanning operations, so it is flagged as limited. * ieee802154: hwsim: Do not check the rtnl * ieee802154: hwsim: Allow devices to be coordinators And finally these two patches are there to allow using hwsim to validate the series. The corresponding userspace code will follow. The series lacks support for forwarding association requests to the user and waiting for feedback before accepting the device. This can be added later on top of this work and is not necessary right now. All of this is based on the initial work from David Girault and Romuald Despres, they are often credited as Co-developpers.
