Bring back 802.11s mesh features to the level previously available
before the recent hostapd version bump. This is mostly to support use
of 802.11s on DFS channels, but also making mesh forwarding
configurable which is crucial for use of 802.11s MAC with other routing
protocols, such as batman-adv, on top.
While at it, fix new compiler warning by adapting 700-wifi-reload.patch
to upstream changes, now building without any warnings again.

Subject: [PATCH 5/7] 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.
