|
|
A kernel module that relays ethernet packets between two devices (similar to a bridge),
|
|
but without any MAC address checks.
|
|
|
|
This makes it possible to bridge client mode or ad-hoc mode wifi devices to ethernet VLANs,
|
|
assuming the remote end uses the same source MAC address as the device that packets are
|
|
supposed to exit from.
