[ drop_packets/test_drop_counters.py ] - Fails due to ValueError in T0 Physical Topology

[Vickyni2]

Description

The test case drop_packets/test_drop_counters.py fails due to Value Error in T0 topology with a physical DUT

Steps to reproduce the issue:

1. Run the test case in a physical DUT.

Describe the results you received: All the below mentioned cases are failed the same value Error.

It's because the command intfstat -j returns N/A. Please manually run the command and check the output.

Hello @bingwang-ms,

I've checked the above command for all the ports return N/A.

admin@dev-msn2700-01:~$ intfstat -j { "Ethernet0": { "RX_BPS": "N/A", "RX_ERR": "N/A", "RX_OK": "N/A", "RX_PPS": "N/A", "TX_BPS": "N/A", "TX_ERR": "N/A", "TX_OK": "N/A", "TX_PPS": "N/A" },
