is RSS and Flow director can work together

[Balakrishnan K]

Hi All,
    I want to use the dpdk application with RSS and flow director.
is possible to use both at a time in application.
In RSS, I am using
action_rss_tcp.types = ETH_RSS_NONFRAG_IPV4_TCP | ETH_RSS_L3_SRC_ONLY | ETH_RSS_L3_DST_ONLY;
to receive the similar traffic to same core.
One specific case where I wanted to distribute the traffic across core, here the incoming traffic having same src and dst IP
Example( src ip : 10.10.10.1 dst ip :20.20.20.2) .
With RSS enabled all the traffic going to end up in one core ,where the remaining cores are being idle impacting the performance.
Planning enable flow director and create rule to distribute the traffic for the combination src /dst ip (10.10.10.1 /20.20.20.2) along with RSS.

if RSS and flow rule having same criteria which one takes the priority .

Regards,
Bala
