We see some flakes in the the XSK test:

Exception| Traceback (most recent call last):
Exception| File "/home/virtme/testing-18/tools/testing/selftests/net/lib/py/ksft.py", line 218, in ksft_run
Exception| case(*args)
Exception| File "/home/virtme/testing-18/tools/testing/selftests/drivers/net/./queues.py", line 53, in check_xdp
Exception| ksft_eq(q['xsk'], {})
Exception| KeyError: 'xsk'

I think it's because the method or running the helper in the background
is racy. Add more solid infra for waiting for a background helper to be
initialized.

v2:
- add patch 1, 3 and 4
- redo patch 5
v1: https://lore.kernel.org/20250218195048.74692-1-kuba@kernel.org
