b615879dbf selftests: drv-net: make linters happy with our imports
Linters are still not very happy with our __init__ files,
which was pointed out in recent review (see Link).

We have previously started importing things one by one to
make linters happy with the test files (which import from __init__).
But __init__ file itself still makes linters unhappy.

To clean it up I believe we must completely remove the wildcard
imports, and assign the imported modules to __all__.

hds.py needs to be fixed because it seems to be importing
the Python standard random from lib.net.

We can't use ksft_pr() / ktap_result() in case importing
from net.lib fails. Linters complain that those helpers
themselves may not have been imported.

ee3ae27721 selftests: drv-net: hds: restore hds settings
The test currently modifies the HDS settings and doesn't restore them.
This may cause subsequent tests to fail (or pass when they should not).
Add defer()ed reset handling.

22d3a63d53 selftests: drv-net: test random value for hds-thresh
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.

Testing bnxt:
    TAP version 13
    1..13
    ok 1 hds.get_hds
    ok 2 hds.get_hds_thresh
    ok 3 hds.set_hds_disable # SKIP disabling of HDS not supported by
    the device
    ok 4 hds.set_hds_enable
    ok 5 hds.set_hds_thresh_random
    ok 6 hds.set_hds_thresh_zero
    ok 7 hds.set_hds_thresh_max

    ok 13 hds.ioctl_enabled_set_xdp
    # Totals: pass:12 fail:0 xfail:0 xpass:0 skip:1 error:0

e514d77334 selftests: drv-net: replace the rpath helper with Path objects
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"

ea4342739d selftests: drv-net: use env.rpath in the HDS test
Commit 29b036be1b ("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.

29b036be1b selftests: drv-net: test XDP, HDS auto and the ioctl 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.

cfd70e3eba selftest: net-drv: hds: add test for HDS feature
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.
