Change Scope

• Adding 800GBASE-2xFR4 and 800GBASE-DR8 PMD
• It is backward compatible

Platform Implementations

• Implementation A: link to documentation and/or
  implementation output.
• Implementation B: link to documentation and/or
  implementation output.

[Note: Please provide at least two references to implementations which are relevant to the model changes proposed. Each implementation should be from separate organizations.].

[Note: If the feature being proposed is new - and something that is being
proposed as an enhancement to device functionality, it is sufficient to have
reviewers from the producers of two different implementations].

Tree View

• [Please provide a view of the tree being modified. It's preferred if a diff format is used for ease of review.]
• [Here are recommended steps to generate the tree view as a diff]

git checkout mychangebranch

Code Review

This pull request adds the ETH_800GBASE_DR8 and ETH_800GBASE_2xFR4 Ethernet PMD types to the openconfig-transport-types YANG module. Feedback was provided to include specification references for both new identities and to capitalize the 'x' in ETH_800GBASE_2xFR4 to ensure naming consistency with existing definitions in the file.

[gemini-code-assist]

It is recommended to include a reference to the relevant IEEE standard (e.g., IEEE 802.3df) for this PMD type, consistent with other entries in this module.

Suggested change

	identity ETH_800GBASE_DR8 {
	base ETHERNET_PMD_TYPE;
	description "Ethernet compliance code: 800GBASE_DR8";
	}
	identity ETH_800GBASE_DR8 {
	base ETHERNET_PMD_TYPE;
	description "Ethernet compliance code: 800GBASE_DR8";
	reference "IEEE 802.3df";
	}

[gemini-code-assist]

For consistency with existing multiplier-based identities in this module (such as ETH_4X10GBASE_LR on line 1199), the 'x' in the identity name should be uppercase. Additionally, adding a reference to the relevant specification (e.g., 800G Pluggable MSA) would improve maintainability.

Suggested change

	identity ETH_800GBASE_2xFR4 {
	base ETHERNET_PMD_TYPE;
	description "Ethernet compliance code: 800GBASE_2xFR4";
	}
	identity ETH_800GBASE_2XFR4 {
	base ETHERNET_PMD_TYPE;
	description "Ethernet compliance code: 800GBASE_2xFR4";
	reference "800G Pluggable MSA";
	}
