Subject: [dpdk-users] Intel X710 (i40e) 802.1ad (0x88a8) packets issue
Date: Thu, 28 Jul 2016 15:15:41 +0600 [thread overview]
Message-ID: <7b0e975e401b40a5989f9bb526f0acec@mail.elsicom.ru> (raw)
Hello,
We have an APP developed and successfully implemented using Intel 82599
cards, but know we would like to switch over to Intel X710-DA4 cards.
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?
