I have some questions and comments.
Question 1
The typical use case of multiple interfaces on this same host is to do RF
segregation in order to improve overall network performance. e.g. divide a
original mesh of 16 radios into 2 meshes of 8 radios each. This multi-radio
host bridges these two small meshes which are on different channels. I can't
see why user would put multiple radios of the same host on the same channel.
They would just interfere with each other very badly.
So, it does not matter whether they have matching mesh setup profile or not.
Two MBSS-es simply can't see each other in air.
Question 2
In MPP where there are multiple mesh interfaces, AP interface and/or Ethernet
interface, how does this "MBSS sharing" work?
a. add both mesh interface in 802.1d bridge, or
b. add either interface in bridge, or
c. sharing can't be used

Subject: [RFC 00/12] MBSS sharing across multiple interfaces
This patchset enables multiple interfaces on the same host to share mesh path
selection and frame forwarding duties. The peering state machine remains
per-interface.
The user interface looks something like:
iw wlan0 mesh join foo shared on
iw wlan1 mesh join foo shared on
As long as wlan0 and wlan1 have a matching mesh setup profile, they will be
considered part of the same MBSS.
This approach is superior to simple 802.1d briding, since mac80211 can
dynamically pick the better link instead of simply disabling an entire port.
The added link knowledge also enables bonding and alternation in the future.
Bob Copeland (6):
mac80211: track and share mesh BSSes among interfaces
mac80211: mesh: add function to tx on all other mbss ifaces
mac80211: use all MBSS interfaces for path selection
mac80211: forward group frames on mbss-shared interfaces
mac80211: add shared-mbss transmit path
mac08211: add shared-mbss receive path handling
Thomas Pedersen (6):
mac80211: assign outgoing interface with nexthop
mac80211: forward frames on correct mbss-shared interface
mac80211: notify bridge when leaving mesh
mac80211: make RMC per-mbss
{nl,mac}80211: specify MBSS sharing on/off
{nl,mac}80211: allow mpath dump to span local MBSS
