9.1 Step 1- Check if the wlan0 Interface is Already Running

This can be done using the "ifconfig" command. Typical output of the command is as shown below: 
root@am335x-evm:~# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 78:A5:04:26:97:3D
          inet addr:192.168.1.4  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:3 errors:0 dropped:0 overruns:0 frame:0
          TX packets:10 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:1240 (1.2 KiB)  TX bytes:1552 (1.5 KiB)

If the wlan0 is present in the list then firmware is already loaded and Step-2 can be skipped.
