TapBridge is designed to bridge a tap device to an ns-3 device.  However, in
USE_BRIDGE mode, the underlying ns-3 device needs to support bridging (support
the function call NetDevice::SendFrom()).  

Some devices may want to be used in emulation, but they are not bridging
devices (e.g. wifi adhoc), so TapBridge needs to compensate for this and use
Send() instead.

see the closed bug 510 for more details.
