[dpdk-dev] Flow Director Example?

[dpdk-dev] Flow Director Example?

[Alex Forster]

Hi guys, apologies if this is the wrong list, but the others look pretty bare.

We have a 32 core server that has two X520-QDA1's NICs with 2x10G ports plugged into each. I'm using 2016.1 (latest stable) with ixgbe 4.3.15 (latest stable). I'm setting up 8 RX queues per port, and I'd like Flow Director in signature mode (?) to place packets into queues based on a hash of destination IPv4 or IPv6 address. However, I can't figure out rte_fdir_conf, and despite a good amount of trial and error, each of my ports are still only using one of the RX queues I set up.

Would anyone be able to point me in the right direction here? Thanks in advance!

Hi Alex

Can you confirm that you are using DPDK? And how do you use DPDK and possibly kernel driver?
I need your detailed topo of how are you using DPDK, as I am a bit confused. Thanks!

Regards,
Helin

Hi Helin, thanks for the reply.

Some code might help me explain myself better-

port->configuration = rte_eth_conf {
        .fdir_conf = {
                .mode = RTE_FDIR_MODE_SIGNATURE,
                .pballoc = RTE_FDIR_PBALLOC_64K,
                .mask = rte_eth_fdir_masks {
                        .ipv4_mask = rte_eth_ipv4_flow {
                                .dst_ip = 0x0,
                        },
                        .ipv6_mask = rte_eth_ipv6_flow {
                                .dst_ip = { 0x0, 0x0, 0x0, 0x0 },
                        },
                },
                .status = RTE_FDIR_REPORT_STATUS,
                .drop_queue = 127,
        },
        .rxmode = {
                .mq_mode = ETH_MQ_RX_NONE,
                .max_rx_pkt_len = ETHER_MAX_LEN,
                .split_hdr_size = 0,
                .header_split   = 0,
                .hw_ip_checksum = 0,
                .hw_vlan_filter = 0,
                .jumbo_frame    = 0,
                .hw_strip_crc   = 0,
        },
        .txmode = {
                .mq_mode = ETH_MQ_TX_NONE,
        },
};




I'm trying to direct packets with the same destination IPv4 or IPv6 address into the same RX queues. I haven't been able to find any examples of using Flow Director with DPDK, so I'm sure I'm doing something obviously wrong here, but I can't figure out what it is.
