4 Subject: [PATCH 5/7] mesh: fix channel switch error during CAC
6 Mesh interface has used its channel parameters that configured
7 during its initialization even after channel switched due to
8 DFS radar detection during CAC which caused channel switch error.
9 This change fixes the error by updating its channel parameters
10 when channel's been changed from initial one.
