I got this error when running ngc_tcp_test.sh.

Cleaning ntuple rules with commands:

for i in {0..100}; do ethtool -N ens5f0np0 delete $i; done
for i in {0..100}; do ethtool -N ens5f1np1 delete $i; done

will fix this error.

@vtlrazin, which version are you using? In the latest versions it should clean the rules.
