Description

Fix the issue #322

Motivation and Context

  1. Add verify_config_laser_frequency to check frequency eariler
    => It doesn't need to re-init CMIS when configure unsupported frequency.

After patch the implementation, it would skip to re-init if only invalid frequency is configured.

Can you please add a description for this function?
Also, are we not planning to handle other frequency grid checks in this function?

Can we move this to configure_laser_frequency?
Since with the current implementation, a port could remain uninitialized forever if the configured frequency is invalid.
Moving the check to configure_laser_frequency will allow to proceed with CMIS initialization with default frequency.

Line 1571:　need_update = self.is_cmis_application_update_required(api, appl, host_lanes_mask)
If the configured frquency is invalid, then it would not change the value of need_update.
If there is some other situation that requires initialization, it will still do the initialization.
If only the frequency is different and the frequency is invalid, I think it is not necessary to do initialize.

Please attach the Unit-test results with user configuring valid frequency and invalid frequency.
