selftests/net: toeplitz test
To verify that this hash implements the Toeplitz hash function.
Additionally, provide a script toeplitz.sh to run the test in loopback mode
on a networking device of choice (see setup_loopback.sh). Since the
script modifies the NIC setup, it will not be run by selftests
automatically.
Tested:
./toeplitz.sh -i eth0 -irq_prefix <eth0_pattern> -t -6
