Answer

Laird has added custom packages to Laird Linux.  These can be found in "menuconfig", under the "Ezurio (formerly Laird Connectivity)" / "Packages" section.  

To enable a Wi-Fi bridge, select the package "BR2_PACKAGE_LRD_WIFI_BRIDGE" and then set the destination interface. For example, set the destination interface to "Ethernet" if you would like to bridge the Wi-Fi to a wired connection.
