3.4.4.2. Promiscuous Mode
In promiscuous mode, most of the MAC functions, especially on the Rx datapath are
ignored; the data is passed on to the client after stripping the preamble and SFD. The
following functions are available in promiscuous mode:

lists the settings required to run in promiscuous mode.
Enables promiscuous operation in the receiver. Destination MAC address is not
filtered.
Disables pad removal from Rx frame.
Receiver forwards the CRC field as received from the network to the client or user
application. Receiver always checks the CRC field and increments the respective
statistics counter and sets the receive frame error bit.
Receiver forwards the pause frames to the client or user application.
Receiver ignores received pause frames.
Transmitter does not modify and does not insert the source MAC address into the
transmit frame from user application.
Receiver accepts and forwards to client all control frames except those for flow
control.
