FIgure out what the bus_id is used for first.

Hello all,

After some more digging I think I've found an incompatibility.

device_add in 2.6.25.20 wants some bus_id, but bus_id seems to not
be assigned anymore, so device_add fails. Therefore, wiphy_register
fails, and then clearly ieee80211_register_hw fails too.

Any ideas how to properly fix this?


Thank you,
 Nikolai

That's great! Care to send some patches for this?

Hello people,

So finally I got it mostly working and usable as AP:

Hardware:
* ASUS WL-500gP (mips) with stock wireless card removed (broadcom).
* New shining Ralink RT2600 Mini-PCI card
Software:
* kernel 2.6.25.20 (openwrt 8.09.1)
* compat-wireless-2009-09-14 (without rfkill_backport and with ugly bus_id fix)
libnl-1.1
hostapd 0.6.9

The led is now even blinking nicely.
Strange though that selecting static IP in the client didn't work,
but using DHCP works fine (it's ok for me now).

Well, it appears the only thing that really needs fixing is dev_set_name()
compatability function, but fixing it properly without making things worse
is a bit beyond my capability at this point. I think someone more familiar
with the code should have a look (a hint is below).
Regarding rfkill_backport, the issue is probably openwrt-specific, becase
there seems to be no way to load modules with circular dependencies without
modprobe (as far as I understand it). Commenting out CONFIG_RFKILL_BACKPORT
in config.mk "fixes" this and I think this issue can not be easily solved
inside compat-wireless package.
