[v3,5/5] app/testpmd: support query RSS config in flow query
Checks
Commit Message
This patch support RSS action in flow query.
It can display the RSS configuration of the specified rule.
For example:
we can create an RSS rule by command "flow create 0 ingress
pattern eth / ipv4 / tcp / end actions rss types ipv4-tcp
l3-src-only l4-dst-only end queues end func symmetric_toeplitz
/ end" and then query it "flow query 0 0 rss"
the log will be follow
RSS:
queues: none
function: symmetric_toeplitz
types:
ipv4-tcp
l3-src-only
l4-dst-only
