SYNOPSIS§

WifiDecap

Ports: 1 input, 1 output

• ETHER — Boolean. If true (this is the default), then push an Ethernet header onto the packet after removing the wifi header.

FromDevice(ath0) -> ExtraDecap() -> FilterTX() -> FilterPhyErr() -> wifi_cl :: Classifier (0/08%0c); //data packets -> wifi_decap :: WifiDecap() -> HostEtherFilter(ath0, DROP_OTHER true, DROP_OWN true) ...
