The test currently runs for ... TPACKET_V1: RX_RING, TX_RING TPACKET_V2: RX_RING, TX_RING TPACKET_V3: RX_RING ... and will output on success: test: TPACKET_V1 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V1 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V3 with PACKET_RX_RING .................... 100 pkts (9600 bytes) OK. All tests passed Reusable parts of psock_fanout.c have been put into a psock_lib.h file for common usage. Test case successfully tested on x86_64.
