It is time to use these to implement a proper scan implementation. There are a few side-changes which are necessary for the soft MAC scan implementation to compile/work, but nothing big. The two main changes are: * The introduction of a user API for managing scans. * The soft MAC implementation of a scan. In all the past, current and future submissions, David and Romuald from Qorvo are credited in various ways (main author, co-author, suggested-by) depending of the amount of rework that was involved on each patch, reflecting as much as possible the open-source guidelines we follow in the kernel. All this effort is made possible thanks to Qorvo Inc which is pushing towards a featureful upstream WPAN support. Example of output: # iwpan monitor coord1 (phy #1): scan started coord1 (phy #1): beacon received: PAN 0xabcd, addr 0xb2bcc36ac5570abe coord1 (phy #1): scan finished coord1 (phy #1): scan started coord1 (phy #1): scan aborted Cheers, Miquèl Changes in v2: * Different way to forward the reason why a scan was terminated, instead of providing two different "commands" we provide the same "scan done" command and aside an attribute, saying whether the scan was aborted by the user or terminated by itself at the end of the required list of (complex) channels to scan.
