[PATCH] Add Realtek 8187B support

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

 



Hi, this patch (made against wireless-testing repository) adds support for
8187B to the rtl8187 module. It is based on code made by Realtek in their
open source driver, plus contains code by initial patch made by John W.
Linville and feedback/fixes to his initial patch by Pavel Roskin (thus I'm
adding them to Signed-offs).

Also I fixed a bug of a missing "priv->vif = vif" in rtl8187_config_interface
that makes kernel oops in transmit code in ieee80211_generic_frame_duration
function.
