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] set mcast_rate in mesh mode
|
|
|
|
The wpa_supplicant code for IBSS allows to set the mcast rate. It is
|
|
recommended to increase this value from 1 or 6 Mbit/s to something higher
|
|
when using a mesh protocol on top which uses the multicast packet loss as
|
|
indicator for the link quality.
|
|
|
|
This setting was unfortunately not applied for mesh mode. But it would be
|
|
beneficial when wpa_supplicant would behave similar to IBSS mode and set
|
|
this argument during mesh join like authsae already does. At least it is
|
|
helpful for companies/projects which are currently switching to 802.11s
|
|
(without mesh_fwding and with mesh_ttl set to 1) as replacement for IBSS
|
|
because newer drivers seem to support 802.11s but not IBSS anymore.
