We are seeing unexpected behaviors regarding BFD on different image versions:
On 202305 image, when shutting down one port channel member, the port channel will be marked as Down, but the BFD Up count remains the same, as if nothing has happened
On 202405 image, when shutting down one port channel member, the port channel will be marked as Down, and the BFD Up count on that LC keeps changing
Currently, we have a test case that covers port channel member flap (code link), but that test case shuts down all interfaces, instead of just one member. Therefore, we should have a test case for testing what will happen when shutting down only one port channel member.
Test Plan
Follow the similar pattern of existing test_bfd_portchannel_member_flap test case but this time we only shut down one port channel member instead of all members.
