Obtain management port speed from system file #337

Open vincentchiang-ec opened 2 days ago

vincentchiang-ec commented 2 days ago

Obtain the actual management port speed from system file /sys/class/net/eth0/speed.

- What I did Currently the management port speed was obtained from the "speed" value in "MGMT_PORT" table of config_db. However, this field has no actual function. This PR is to obtain the actual management port speed from system file "/sys/class/net/eth0/speed".

- How I did it Add a function to obtain the actual management port speed from system file "/sys/class/net/eth0/speed".

- How to verify it Run snmpwalk to get if high speed, make sure the management port speed is correct.
