Replace the simple modulo math with the real indirection table
read from the device. This makes the tests pass for mlx5 and
bnxt NICs.

Now that we have YNL support for RSS accessing the RSS info from
C is very easy. Instead of passing the RSS key from Python do it
directly in the C code.

Rewrite the existing toeplitz.sh test in Python. The conversion
is a lot less exact than the GRO one. We use Netlink APIs to
get the device RSS and IRQ information. We expect that the device
has neither RPS nor RFS configured, and set RPS up as part of
the test.

The GRO test can run on a real device or a veth.
The Toeplitz hash test can only run on a real device.
Move them from net/ to drivers/net/ and drivers/net/hw/ respectively.
There are two scripts which set up the environment for these tests
setup_loopback.sh and setup_veth.sh. Move those scripts to net/lib.
The paths to the setup files are a little ugly but they will be
deleted shortly.
toeplitz_client.sh is not a test in itself, but rather a helper
to send traffic, so add it to TEST_FILES rather than TEST_PROGS.
