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.
Fixes: 0a3ec87a66 ("hostapd: update to latest Git hostap_2_9-1238-gdd2daf0848ed")

Subject: [PATCH 4/7] mesh: do not set offchanok on DFS channels in non-ETSI
|
|
|
|
mac80211 does not allow mgmt tx to use off channel on
|
|
DFS channels in non-ETSI domain, because it will invalidate
|
|
CAC result on current operating channel.
|
|
(mac80211 commit: 34373d12f3cbb74960a73431138ef619d857996f)
|
|
Hence don't set offchanok for mgmt tx in case of DFS channels
|
|
in non-ETSI.
