Re: Problems with MA111 and hotplug

Previously I posted a patch to resolve a problem I was having with MA111, 
hotplug and FC3. Just as you found, none of the suggested remedies worked 
for me. What seems to be happening is that the drivers have difficulty 
getting out of fwload state, and subsequent commands produce the 
"implementation failure" message.

I find that I need the same patch under FC4 which is to add one line to 
/etc/wlan/shared.

Extract from previous post relating to FC3:

In /etc/wlan/shared
        wlan_enable()
        .......
        nsdname=`wlan_nsdname $1`
        if ! ${nsdname}_fwload $1 ; then
                ${ECHO} "Firmware failed to load for device $1"
                return 1
        fi
        # Enable the interface
        # ADD THE FOLLOWING LINE
        $WLANCTL $1 lnxreq_ifstate ifstate=disable
        result=`$WLANCTL $1 lnxreq_ifstate ifstate=enable`

The patched file /etc/wlan/shared is called by /etc/hotplug/wlan.agent and 
also by /etc/init.d/wlan.

I am not sure why this works, except that before the patch the result of the 
"wlanctl-ng  wlan0 lnxreq_ifstate ifstate=enable" in the above script was 
"implementation failure" as shown below:
Jun  6 21:04:09 myntech kernel: hfa384x_docmd: ctlx failure=REQ_FAILED
Jun  6 21:04:09 myntech wlan.agent[19532]: Failed to enable the device, 
resultcode= implementation_failure .
Jun  6 21:04:09 myntech wlan.agent[19532]: WLAN Could not bring up wlan0
Jun  6 21:04:09 myntech kernel: hfa384x_drvr_start: cmd_initialize() failed, 
result=-5
Jun  6 21:04:09 myntech kernel: prism2sta_ifstate: hfa384x_drvr_start() 
failed,result=-5


After the patch the wlan0 interface is now stable, and trouble-free.

I notice that after un-plugging and re-plugging, sometimes the network 
routing table entries get lost. To get going again I must do the following:

service wlan restart
service network restart

and the link and network are restored.
