Fix remove source port check

[georgmittendorfer]

Description

Removed source port check for receiving data from neighbors (TCP and UDP). That allows to receive data from neighbors that use other source ports than target ports.

Hopefully fixes #961 UDP Peering Source Port Problem.

Type of change

• Enhancement (a non-breaking change which adds functionality)

How Has This Been Tested?

• Feature is unit tested.
• Feature for UDP is manually end to end tested.
• Feature for TCP is not end to end tested.

Checklist:

• My code follows the style guidelines for this project
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes

Discussion:

• Would be great if someone could end 2 end test this to verify that the fix works not only in my setup.
• I am not sure, if the fix makes sense for TCP. TCP worked properly before in my setup. I can change the fix to UPD only if desired.
• Adding/removing neighbors works as before. No changes there.
