4-address header support

4 address header support is an important feature for WDS.

WDS (Wireless Distribution System) is an AP mode which allows APs to connect to one-another without cables. It provides routing and repeating modes, and requires 4 address fields in each frame in order to operate correctly. For more information on WDS, see Tom's Networking

Refer to AboutWDS for further information about the current status.
