AFP peers list

AF_PACKET has an IPS mode were interface are peered: packet from on interface are sent the peered interface and the other way. The AFPPeer list is maintaining the list of peers. Each AFPPeer is storing the needed information to be able to send packet on the interface. A element of the list must not be destroyed during the run of Suricata as it is used by Packet and other threads. More...
