[PATCH WIP] rtl8187b support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello!

I'm posting this patch mostly to share my results so far and take that
burden from me.  I have no desire to take over maintenance of that
driver or to answer any support requests.

This is a combination of the patches from
https://bugzilla.redhat.com/show_bug.cgi?id=432280 ported to the current
linux-wireless.  I removed all procfs support changes for make the patch
smaller, but it's still 40k.

The driver loads and initializes the device successfully.  Bringing the
interface up is very slow (10 to 20 seconds), but it works.  Scanning
works, but wpa_supplicant reports time out trying to authenticate with
the AP.  Quality in scan results is always 0/100.  Association to APs
without encryption works, but the packets don't go through.  Unloading
the module is working.
