hds.py has been testing 0(set_hds_thresh_zero()),
MAX(set_hds_thresh_max()), GT(set_hds_thresh_gt()) values for hds-thresh.
However if a hds-thresh value was already 0, set_hds_thresh_zero()
can't test properly.
So, it tests random value first and then tests 0, MAX, GT values.

The single letter + "path" helpers do not have many fans (see Link).
Use a Path object with a better name. test_dir is the replacement
for rpath(), net_lib_dir is a new path of the $ksft/net/lib directory.
The Path() class overloads the "/" operator and can be cast to string
automatically, so to get a path to a file tests can do:
path = env.test_dir / "binary"

Commit 29b036be1b0b ("selftests: drv-net: test XDP, HDS auto and
the ioctl path") added a new test case in the net tree, now that
this code has made its way to net-next convert it to use the env.rpath()
helper instead of manually computing the relative path.

Test XDP and HDS interaction. While at it add a test for using the IOCTL,
as that turned out to be the real culprit.

Netdevsim needs a sane default for tx/rx ring size.
ethtool 6.11 is needed for the --disable-netlink option.

HDS/HDS-thresh features were updated/implemented. so add some tests for
these features.
HDS tests are the same with `ethtool -G eth0 tcp-data-split <on | off |
auto >` but `auto` depends on driver specification.
So, it doesn't include `auto` case.
HDS-thresh tests are same with `ethtool -G eth0 hds-thresh <0 - MAX>`
It includes both 0 and MAX cases. It also includes exceed case, MAX + 1.
