## activateVAP
##
## This script is used to activate a VAP that was created earlier.
## Activation involves bringing the interface up, associating with
## a bridge, and configuring the security mode. The VAP MUST EXIST
## prior to calling the activate script.
##
## The form of the command is
##
## activateVAP <vap> <BR> <Security> <SEC Args> <WSC> <VAP_TIE>
##
## Where
## vap: Vap ID (e.g. ath0)
## BR: Bridge to join (or - if not bridged)
## Security: Security mode (WEP,WPA,WSC,NONE)
## Sec Args: File containing security configuration. For WPA this is the hostapd
## conf file. For WEP this is a list of iwconfig commands setting the
## keys.
##
## Examples:
## Open Access Point
## activateVAP ath0 br0 NONE
## WPA Access Point
## activateVAP ath1 br0 WPA wpa2-psk.conf
## WEP Station
## activateVAP ath0 br0 WEP wep.conf
