And there is a problem occurred. We cannot receive any "0x88a8" (802.1ad) traffic. As we see from statistics using function rte_eth_stats_get(): rx_good_bytes = 204681 rx_unicast_packets = 266 rx_unknown_protocol_packets = 266 rx_size_65_to_127_packets = 12 rx_size_128_to_255_packets = 24 rx_size_256_to_511_packets = 48 rx_size_512_to_1023_packets = 98 rx_size_1024_to_1522_packets = 84 They are successfully received on a port, but then somewhere disappered. So it's not possible to get them by rte_eth_rx_burst() func. It's always 0 packets readed. The same traffic flow received and handled without any troubles on 82599 cards using ixgbe compiled into igb_uio. What can be wrong there and what configuration may be I have missed?
