I am going through the w12xx code (v 3.3) and I came across various pieces of codes for DUMMY PACKETS

could some explain to me what these packets are used for ???

thanks

    Hi Bernard,

    It is really internal implementation of dynamic memory mechanism, and has nothing to do with WLAN standard at all.

    When the FW wants to transfer memory blocks from tx pool buffers to rx (to have more memory for the rx), it requests the driver to transmit a dummy packet, that is done for internal synchronization between the driver and firmware (just Algorithm implementation)

    Regards,
