rte flow rule not clear with DPDK 21.11 and Intel E810

[Filip Janiszewski]

Just updating on other similar issue I'm finding, it appears this rte
flow rule is completely broken for Intel E810 and most probably useless,
for example, this rule works:

.
testpmd> flow create 0 ingress pattern eth / ipv4 / tcp dst is 2044 /
end actions queue index 1 / end
Flow rule #4 created
.

But the UDP version does not work:

.
testpmd> flow create 0 ingress pattern eth / ipv4 / udp dst is 51005 /
end actions queue index 1 / end
Flow rule #1 created
.

Also vlan id based filtering do not work, ip ranges (using spec+last) do
not work et cetera.

Am I doing something wrong with testpmd or anybody can confirm that this
is just not working until fixed?

Thanks
