I saw below error message if I turn on/off wifi hotspot quickly.  
D/WifiHW  (   85): Unable to unload driver module "itm_ap.ko": No such file or directory
D/WifiHW  (   85): Unable to unload driver module "itm_sta.ko": No such file or directory
W/WifiHW  (   85): insmod filename=/system/lib/modules/itm_sta.ko args= 
E/SoftapController(   85): Softap fwReload - failed: -1
I/Gecko   ( 1899): -*- WifiWorker component: Disable Wifi tethering result: netd command error

I think this should be owned by partner.
Hi xinhe, may I have your comment on netd command error ?

You can ignore this error.

This is our soft ap bug. Turn off/on soft ap quickly, it will be fail to insmod soft ap ko.

We will update wifi code soon, but I don not know whether this will be in this update.
Anyway, I will take it.

I guess it take more time to inmod and rmmod.
At last wifi_unload_driver is called to rmmod host ap ko file.

Trout has two ko files. itm_ap for host ap. itm_sta for wifi.

Does patch in 989717 will fix this bug?
I think timing issue should be fixed in wifi_load_driver()/wifi_unload_driver() in wifi.c. 
0.2 seconds may not long enough in wifi_unload_driver().
Hi Vincent,
As post in comment 5, gecko call wifi_unload_driver at last. This will unload ap/sta driver in wifi_itm.c.
It take more time to see WifiHW log. 
After togger soft ap many times, soft ap will be disble in UI. Click panel to enable soft ap immediatelly, but soft ap disable automaticlly.
