testpmd - configuration of the fdir filter

[Jan Fruhbauer <fruhbauer@invea.com>]

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
