Subject: [PATCH] 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.
