Thanks for the work Uli, but I couldn't get it to act any differently. I didn't have the git-fu to magic your patchset on to wireless-dev, so I tried it three ways, first trying to git clone your whole thing and moving to the zd1211rw-dev branch ... but even when I was on that branch, there was no drivers/net/wireless/mac80211 dir. Then I tried taking a snapshot of the drivers/net/wireless/mac80211/zd1211rw dir from the gitweb interface and replacing it by hand using quilt, and lastly saving raw copies of your 17 patches and using quilt to put them on top of wireless-dev one by one. The last two methods worked okay but the resulting module didn't act any differently in terms of what it picked up on Monitor mode. I confirmed it was the new module with md5sum. > This isn't going to work properly when you add a sta interface and then > a monitor interface, which afaict the driver doesn't prevent in > zd_mac_open.

This is a bit of a general issue that has been discussed a couple of times, not really to a resolution: how to deal with conflicting demands of multiple interfaces on the same rx hardware. I guess it wants it to be that if any interface is in Monitor then the hardware promisc is enabled. IFF_PROMISC was discussed to be another way to select genuine promisc rx as well. FWIW my script looks like this: modprobe -r zd1211rw-mac80211 modprobe -r rc80211_simple modprobe -r mac80211 modprobe zd1211rw-mac80211 sleep 2s ifconfig wlan0 up echo -n mon0 >/sys/class/ieee80211/phy0/add_iface iwconfig mon0 mode monitor iwconfig mon0 channel 6 ifconfig mon0 up -Andy - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
