Enables Proxy ARP handling for MUs. Proxy ARP is provided for MU's in
PSP mode whose IP address is known. The WLAN generates an ARP reply
on behalf of a MU, if the MU's IP address is known. The ARP reply
contains the MAC address of the MU (not the MAC address of WLAN
Module). Thus, the MU does not awaken to send ARP replies (helping to
increase battery life and conserve bandwidth). If an MU goes into PSP
mode without transmitting at least one packet, its Proxy ARP will not
work for the MU. This option is selected by default.
Enables Shared-Key Authentication for all enabled WLANs on the system.
Shared-key authentication is strongly discouraged. This option is enabled
in setups where there are legacy mobile units which can only support this
authentication method.
