Hi Damien,

With your latest changes to iwi, the driver is working as well as the
one in 3.8.

The only issue is: my card does not work reliably. After a reboot the
card works for a while. During that time ifconfig iwi0 looks like this:

iwi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        lladdr <removed>
        groups: egress 
        media: IEEE802.11 autoselect (DS11)
        status: active
        ieee80211: nwid my_ap chan 1 bssid <removed> nwkey <not displayed> 100dBm 
        inet 192.168.0.7 netmask 0xffffff00 broadcast 192.168.0.255
        inet6 fe80::213:<removed>%iwi0 prefixlen 64 scopeid 0x2

But eventually (some times it takes hours) the card loses the
connection. At this stage I cannot ping the base, then when I
re-init the card it does not see the network.

% ping -i 20 192.168.0.1

Bringing ifconfig iwi0 down or rerunning netstart does not
help. Suspending the system does not help. The only thing that does help
is a reboot.

Just for completeness sake, below is the dmesg from the kernel I built
from last night CVS.

Thanks
Greg
