Hi Andrey
First of all, Thanks for your works to enable the ath5k support
80211s. I just testing them with the newest wireless-testing tree and
meet some problems:
The Atheros chipset what I used is one AR2413 cardbus card and one
AR5414(the lspci show it as AR5413 but debug message show is as
AR5414) , after apply the patch, I waked the up them by follow
commands:
iw dev wmaster0 interface add mesh type mp mesh_id 12345
iwconfig mesh channel 1
ifconfig mesh 192.168.3.80/192.168.3.81
but there is no beacon was send from any of them, after input "iw dev
mesh station dump"
it also no station was found,(PS:the two PC are very close), ping each
other also no response.
After roughly browse the ath5k code and the patch, I have below questions:
1. From the patch, there is no any place to set the sc->opmode's
value to IEEE80211_IF_TYPE_MESH_POINT.
2. it also haven't found code to enable/trigger "beacon send" in
MESH_POINT mode.
So I think maybe this patch can make ath5k work in mesh mode if some
mesh point(with b43 or zd1211rw) has been waked up early. because it
can correctly deal with the RX mesh packet. but it can't work
independent in a pure ath5k mesh network, cause none can send beacon
correctly, and hence they can't set up link each other.
