Add support for remote speed advertisement, such that users could easily
identify the connection issues when autoneg is enabled.

HLD: sonic-net/SONiC#924

Signed-off-by: Dante Su dante.su@broadcom.com

What I did

Add support for remote speed advertisement

How I did it

Implementation is done according to the AutoNeg HLD

How to verify it

Built-in unit tests
Manual tests

Please update the description with old CLI output and new CLI output.
The CLI output change will impact existing systems in production and automation frameworks that rely on a specific output pattern. Has this been considered?

Why do you need to change the test case name to eth9 when it is using etp9?

This logic will not work for switches that have less than 1G speed (e.g mgmt switches which run sonic) Please consider the use case as well.

there is already port_oper_speed_get() to get the speed, so why is this if check required?
