Extend HW timestamp tests to check that ioctl interface is not broken
and configuration setups and requests are equal to netlink interface.
Some linter warnings are disabled because of ctypes classes.

Add simple tests to validate that the driver sets up timestamping
configuration according to what is reported in capabilities.
For RX timestamping we allow driver to fallback to wider scope for
timestamping if filter is applied. That actually means that driver
can enable ptpv2-event when it reports ptpv2-l4-event is supported,
but not vice versa.
