examples/ptpclient: revert frequency adjustment

The commit 6d55af611fd5 ("examples/ptpclient: add frequency adjustment")
includes some GPL-licensed code and therefore cannot be applied to the
DPDK. Therefore, revert that commit.

By reverting this commit, the basic functionality (PMD support for
high-precision clocks) will not be affected, but its accuracy will be
reduced to the microsecond level.

examples/flow_filtering: introduce use cases snippets

These code snippets demonstrate rule creation using
template and non-template APIs.
They include functions that enable developers to create rules.
The purpose of providing these snippets is to allow developers
to reuse them, thereby saving time and effort during the
implementation of flow rules.

The code snippets are categorized based on their usage and can be copied,
paste and modified to suit any requirements.
The snippets provided here are kept up to date and are being compiled
along with the rest of the examples.

There is a skeleton that demonstrates rule creation
using both template and non template APIs.

Developers can change the functions in the skeleton to the corresponding
snippet functions with the appropriate suffix and create rules using the
snippets themselves for easy testing. Each snippet has the same functions
to implement the actions and patterns for the corresponding feature.
