The setup_loopback and setup_veth use their own way to create namespace. So let's just re-define server_ns/client_ns to unique name. At the same time update the namespace name in gro.sh and toeplitz.sh. As I don't have env to run toeplitz.sh. Here is only the gro test result. # ./gro.sh running test ipv4 data Expected {200 }, Total 1 packets Received {200 }, Total 1 packets. ... Gro::large test passed. All Tests Succeeded!
