Flow rules performance with ConnectX-6 Dx

[Дмитрий Степанов]

For some reasons I'm not able to create group 1 / jump action. I get this
error:

testpmd> flow create 0 ingress pattern end actions jump group 1 / end
port_flow_complain(): Caught PMD error type 16 (specific action): cannot
create jump action.: Operation not supported
testpmd> flow create 0 ingress group 1 pattern eth / ipv4 dst is 10.0.0.2 /
end actions drop / end
port_flow_complain(): Caught PMD error type 1 (cause unspecified): cannot
get table: Cannot allocate memory

This looks similar to

I've checked UCTX_EN bit - and it its already set within NIC:

mstconfig -d 0000:c1:00.0 q | grep UCTX_EN
         UCTX_EN                             True(1)
