Summary

when use switch 1 test case AgentPacketSendTest.PortTxEnableTest, it reports error:
F20260131 22:24:09.467856 69362 MultiSwitchHwSwitchHandler.cpp:416] Check failed: !transaction
*** Check failure stack trace: ***

Motivation

The test case failed because switch_id now need to be provided via command-line arguments according to the new requirements, but this wasn't updated. I am now applying the changes based on this commit.
