[PortsOrch] Failures seen during port startup: getPortOperSpeed: Failed to get oper speed

[vaibhavhd]

Description

Port startup throws errors when portsorch attempts to getPortOperSpeed. This can potentially cause Log Analyzer failures in regression tests. No known test failures at this point (this can change with new results).

The issue has started after a recent PR which added support for getPortOperSpeed : sonic-net/sonic-swss#1714

This seems to be due to SAI_PORT_ATTR_OPER_SPEED not yet supported on all the platforms, and hence the SAI_STATUS_ATTR_NOT_IMPLEMENTED_0 is received instead of expected SAI_STATUS_SUCCESS.

Steps to reproduce the issue:

1. Install latest master on SONiC DUT (tried on 7260)
2. Flap any one of the ports.
3. Check syslog.

Describe the results you received:
