Promiscuous packet queue

File: csp/csp_promisc.h

Description: Promiscuous packet queue. This feature is used to enable promiscuous mode for incoming packets, e.g. router, bridge. If enabled, a copy of all incoming packets are cloned (using csp_buffer_clone()) and placed in a FIFO queue, that can be read using csp_promisc_read().
