Comment:

 The issue with uap0 being created by default is still present, but we
 think we've convinced Marvell to fix that. For now we have a workaround in
 our builds.

 The scan dwell times in 8787 were also quite high. We pushed a kernel
 patch (from upstream) to sanitize these values and the interruptions
 caused by scans are almost unnoticable now. Newer upstream kernels have a
 more complete solution where channels are scanned a bunch at a time, at
 intervals, to interrupt connectivity even less.
