1. In some cases iwconfig_get_wep_key() appends "enc open" to iwconfig's command line without a necessity.
-> iwconfig wlan0 key restricted s:mykey enc open
key_SSID2="s:mykey key restricted"
-> iwconfig wlan0 key s:mykey key restricted enc open
According to "man iwconfig" these key stings are valid, but iwconfig.sh appends "enc open" to them.
2. It would be very good, if iwconfig.sh displayed the command line when the net script was started with "-v" key. It was unexpectedly for me, that iwconfig.sh appends something to the command line without any notice.
