Where is<br />the problem?<br /><br />The goal is to make life simpler for drivers. Dealing with WE is not<br />easy and even if everything which ieee80211 will do is allowing drivers<br />to register their handlers during allocation of ieee80211_device by<br />simply setting pointers to their functions (in ieee80211_device or<br />somewhere), it will be easier (see the thread at<br /><a href="http://oss.sgi.com/projects/netdev/archive/2004-06/msg00463.html">http://oss.sgi.com/projects/netdev/archive/2004-06/msg00463.html</a> to<br />understand what I mean).<br /><br />But I agree this is something we can argue about.
