[$] iwd: simplifying WiFi management

It has been nearly 13 years since Jeff Garzik proclaimed that Linux was "proving itssuperiority in the area of crappy wireless (WiFi) support".Happily, the situation has improved somewhat since then, but that doesn'tmean that things can't get better yet. During the Embedded LinuxConference portion of the 2018Open Source Summit Europe, Marcel Holtmann described the work beingdone to create iwd, a new systemfor configuring and managing WiFi connections. If this project has its way, future users will have little roomfor complaint about how WiFi works on Linux systems.
