  • What I did
    Removed the dependency on the "Ethernet" string in the SONiC code base and added support
    for extending the front panel port name pattern.

  • How I did it

  1. Introduced FRONT_PANEL_PORT_PREFIX_REGEX that extends the old FRONT_PANEL_PORT_PREFIX ("Ethernet")
  2. Updated all the relevant usage of the "Ethernet" throughout the code base to use the new regex pattern
  • How to verify it
    Pass all UT and CI testing.

  • Why I did it
    In order to support distinguishing between different types of front panel ports in a maintainable fashion.
    Specifically, we are planning to bring up a system with 'service' ports (in addition to the regular ethernet data ports) - these
    are lower speed ports that used for connection to accelerators, internal loopbacks and more.

@kcudnik @qiluo-msft - I updated the code with the new comments and rebased since the dependency fix was already merged to master by a different commit (you can check my comment there). Please check, thank you!
