3.18 is working - 4.1/4.4 is not working
trying to upgrade a few things here, and I've discovered STP doesn't flow over my atheros wds links with the latest builds on stuff
is this a known issue of some sort ?
using 4addr type wds links
i've got a few gadgets, and have been doing various tests to try understand where it is and is not flowing
after many combinations and permutations, the conclusion is
anything running the older 3.18 kernel based builds all seem to work fine
but anything setting up 4addr wds link using a 4.1 or 4.4 based setup, stp doesn't flow over the 4addr client connection
but, it does flow from a 4.x system runnign the ap side of the link, to a 3.x running the client side of the link
ive tested this with nanostation, picostation, and unifiac units
the unifiac is the reason I'm trying to update things, to a kernel rev that has unifiac support
groz: you probably should file a bug at http://bugs.lede-project.org/ - since the behaviour changed between kernel versions there must be some bug .

i've been reading up a bit, and it seems upstream broke 4addr mode at 3.9
what ath, ath9k, 10k?
both
happens on my 10K units with 4.1 or 4.4
and on my 9k units with 4.1 of 4.4
but with 3.18 the 9k stuff works fine
I just cant get the new 10K unit to bridge properly
Ive built a considerable number of different configurations to try isolate and identify
I haven't tried that config, but someone else was complaining about WDS with ath10k, seems it mostly worked for them though.
what happens is, with the wds link in place
each unit becomes its own root bridge
because stp isn't flowing over the link
so they dont honor the overall network root bridge
you wont notice this if you aren't using stp
my environment depeds on it, because I have a high capacity main link, and a lower capacity backup link
between the two networks

my test case is using a pair of unifi ath10K units, which were not backported to the 3.18 revs, hence i build something newer
my current live links are using ubiquity loco for the backup link, and fiber optic for the primary
but if my power goes out at the midpoint (happens once in a while), then I need the network between the observatory and the house to fail onto the wifi links transparently
dunno...I have to run, see you all laters.
that wont work correctly without stp working correctly
