Description of PR
After debug and investigation, this failure of "test_everflow_testbed" on dualtor A-A including two issues:
the mux status is standby on the selected DUT.
the test pkts are not sent to selected DUT, which has everflow rule config.
The rootcause of 1 is due to BGP shutdown. In the script, it tries to shutdown all BGP during setup, which makes T1 not reachable from the TOR. Then the DUT moves itself into standby mode. That's from the design of mux state machine.
The rootcause of 2 is similiar to the following issue:
#8158
We need fall back to active-standby mode to test this scenario for
active-active ports.
