2.5GBbit/s interface should be supported

[niloda]

Nowadays many SFP module manufacturers have 2500Base-X type devices in their portfolios that work at 2.5Gbps speed, and many switch / router manufacturers have products with 2500Base-T interfaces in their catalog. In some specific use cases, they are also used by MW devices, so the model should support these types.

Proposal:

• add the types 2500BASE-T and 2500BASE-X to the pmd-name object attribute of the pmd-kind grouping
• add the value '2.5GBbit/s' to the speed attribute comment of pmd-kind grouping
• add the 2500BASE-T and 2500BASE-X types to the description of the module

As a further improvement, the pmd-name and pmd-kind attributes could be more strongly typed by transforming them from string to identity.

Decision on the 5G-xhaul call on 10th of November 2021:

• Changing the comment of the pmd-kind::pmd-name attribute from "To be chosen from the following list of PMD names according to IEEE 802.3 '10BASE5', ... '1000BASE-T', '10GBASE-X', ..." to "To be chosen from the following list of PMD names according to IEEE 802.3 '10BASE5', ... '1000BASE-T', '2500BASE-T', '2500BASE-X', '10GBASE-X', ..."
• Changing the comment of the pmd-kind::speed attribute from "Line speed of the PMD. Value to be chosen from '2Mbit/s', ... , '1000Mbit/s', '10Gbit/s', ..." to "Line speed of the PMD. Value to be chosen from '2Mbit/s', ... , '1000Mbit/s', '2500Mbit/s', '10Gbit/s', ..."
• Changing the comment at the root element from "This model is for vendor agnostic management of Ethernet PHY interfaces. Supported: '10BASE5',..., '1000BASE-T', '10GBASE-X', ..." to "This model is for vendor agnostic management of Ethernet PHY interfaces. Supported: '10BASE5',..., '1000BASE-T', '2500BASE-T', '2500BASE-X', '10GBASE-X', ..."
