2.6.25 kernel & compat-wireless-2009-09-14

[Nikolai ZHUBR]

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

FIgure out what the bus_id is used for first.

Hmm, don't know, but the following helps and wlan0 appears:

Isn't that exactly what dev_set_name() is/was supposed to do?

Well, probably yes, but still it doesn't set bus_id, I've checked.
Probably it needs some correction.

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).

 Nikolai

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