Drop outdated and by now broken patchset originally supplied by Peter Oh in August 2018 but never merged upstream. Instead add the more promissing rework recently submitted by Markus Theil who picked up Peter's patchset, fixed and completed it and added support for HE (802.11ax) in mesh mode. This is only compile tested and needs some real-life testing.

Subject: [PATCH 12/19] mesh: fix channel switch error during CAC
|
|
|
|
Mesh interface has used its channel parameters that configured
|
|
during its initialization even after channel switched due to
|
|
DFS radar detection during CAC which caused channel switch error.
|
|
This change fixes the error by updating its channel parameters
|
|
when channel's been changed from initial one.
