The mentioned test uses a few Kconfig still missing the net config, add them.

The pmtu.sh test tries to detect the tunnel protocols available in the running kernel and properly skip the unsupported cases.

In a few more complex setup, such detection is unsuccessful, as the script currently ignores some intermediate error code at setup time.
