hello - i've successfully run the "apply-wireless.sh" script and booted 
into a rebuilt kernel.  the system has an intel 9560 device which i 
usually used with if_iwm.

i am able to successfully unload if_iwm and load if_iwlwifi.ko. after 
updating my rc.conf to use the iwlwifi0 device and running "service 
netif start" i see the following output in my dmesg buffer:

lan0: Ethernet address: d8:3b:bf:82:d4:4e
lo0: link state changed to UP
iwlwifi0: lkpi_ic_getradiocaps: Adding chan 1/2412/0/0/0 returned error 55
iwlwifi0: lkpi_ic_getradiocaps: Adding chan 36/5180/0/0/0 returned error 55

wlan0: ieee80211_newstate_cb: INIT -> SCAN arg 0
wlan0: sta_newstate: INIT -> SCAN (0)


the NIC isn't able to associate with any SSID's and /var/log/messages 
contains:
Sep  9 20:52:15 colony wpa_supplicant[76640]: ioctl[SIOCS80211, op=103, 
val=0, arg_len=128]: Operation now in progress
Sep  9 20:52:15 colony wpa_supplicant[76640]: wlan0: 
CTRL-EVENT-SCAN-FAILED ret=-1 retry=1


i haven't had a chance to dig into what "error 55" is but posting here 
to see if this is a known issue.  here is my systems dmesg after i 
unload if_iwm and load if_iwlwifi:

this dmesg is from after me running "service netif start"
https://termbin.com/bpkk

and finally here's a termbin of /var/log/messages.

happy to test any patches or run additional debug steps, i've got this 
system setup as a zfs bootenv.
