How to successfully write a flow filter for 82599

[Qi]

Hi,

I would like to use flow director (on 82599) to steer packets to individual queue. However, I couldn't write a flow filter rule to the NIC successfully. I have tried both the perfect filter and the signature one, unfortunately, neither of them could work.

The error is:

fdir_write_perfect_filter_82599(): Timeout writing flow director filter, or

fdir_add_signature_filter_82599(): Timeout writing flow director filter.

The OS on my server is ubuntu 16.04, the DPDK version is 18.11

the filter configure I am using is as follows:

struct rte_eth_fdir_filter ff;

memset(&ff, 0, sizeof(struct rte_eth_fdir_filter));

ff.input.flow.tcp4_flow.ip.dst_ip = 0xA040EC7

ff.input.flow.tcp4_flow.dst_port = 0x1A0A

ff.action.report_status = RTE_ETH_FDIR_REPORT_ID;

ff.action.behavior = RTE_ETH_FDIR_ACCEPT;

ff.action.rx_queue = 1;

ret = rte_eth_dev_filter_ctrl(port_id, RTE_ETH_FILTER_FDIR, RTE_ETH_FILTER_ADD, &ff);

I am not sure where the problem is. Could you help me out. Thanks.​
