James, Can you post a patch that will build? or did you just want feedback on the current state of the patch? Thanks, -- ~Randy a. in ieee80211/Makefile, there is nothing for ieee80211_module.o: ieee80211-objs := \ ieee80211_module.o \ b. in wireless/Makefile, it needs to pull in ieee80211, e.g.: --- Makefile~80211_netstack 2004-12-24 13:35:50.000000000 -0800 +++ Makefile 2005-02-07 18:37:49.000000000 -0800 @@ -2,6 +2,8 @@ # Makefile for the Linux Wireless network device drivers. # +obj-$(CONFIG_IEEE80211) += ieee80211/ + obj-$(CONFIG_STRIP) += strip.o obj-$(CONFIG_ARLAN) += arlan.o
