testpmd - configuration of the fdir filter

Hi,

I want to use the fdir filtering on a NIC based on the Intel 82599. I have tested the testpmd application. I configured masks and added a filter but the fdir filter never matched any packet. I even tried different masks and filters (with/without ports, TCP/UDP flow, IP prefixes, ...), but it never worked. Here is an example of commands I used during testing:

./testpmd -c 0xff -n 2 -- -i --rxq=2 --txq=2 --pkt-filter-mode=perfect --portmask=0x3 --nb-ports=2 --disable-rss
testpmd> port stop 0
testpmd> flow_director_mask 0 vlan 0x0000 src_mask 255.255.255.255 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF dst_mask 255.255.255.255 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF testpmd> flow_director_flex_mask 0 flow all (0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)
testpmd> port start 0
testpmd> flow_director_filter 0 add flow ipv4-tcp src 1.0.0.1 1 dst 2.0.0.1 1 vlan 0x0 flexbytes (0x00,0x00) fwd queue 1 fd_id 1
testpmd> start

Then I sent generated traffic (simple packets with ethernet/IP/TCP headers) with parametrs I specified in the flow_director_filter to the NIC port 0 and all packets arrived to the queue 0.

Please, could you advise me what I am doing wrong? Maybe some other configuration I didn't notice?

Regards,
Jan

I'm getting a fdir filter programming error after I do this --

./testpmd -c ffffffff -n 4 -- -i --pkt-filter-mode=perfect --rxq=2 --txq=2 --portmask=0x3 --nb-ports=2 --disable-rss

testpmd> port stop all

testpmd> flow_director_mask 0 vlan 0xefff src_mask 255.255.255.255 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF dst_mask 255.255.255.255 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF

testpmd> flow_director_filter 0 add flow ipv4-udp src 192.168.10.100 dst 192.168.10.101 vlan 0x1 flexbytes (0x00,0x00) fwd queue 1 fd_id 1

PMD: fdir_write_perfect_filter_82599(): Rx Queue=1 hash=10529

PMD: fdir_write_perfect_filter_82599(): Timeout writing flow director filter.

PMD: ixgbe_add_del_fdir_filter(): Fail to add FDIR filter!

flow director programming error: (Connection timed out)

Any ideas? Debug?

Thanks
