charset="utf-8" The ability to describe the physical ports of Ethernet devices is useful to describe multi-port devices, as well as to remove any ambiguity with regard to the nature of the port. Moreover, describing ports allows for a better description of features that are tied to connectors, such as PoE through the PSE-PD devices. Introduce a binding to allow describing the ports, for now with 2 attributes : - The number of lanes, which is a quite generic property that allows differentating between multiple similar technologies such as BaseT1 and "regular" BaseT (which usually means BaseT4). - The media that can be used on that port, such as BaseT for Twisted Copper, BaseC for coax copper, BaseS/L for Fiber, BaseK for backplane ethernet, etc. This allows defining the nature of the port, and therefore avoids the need for vendor-specific properties such as "micrel,fiber-mode" or "ti,fiber-mode". The port description lives in its own file, as it is intended in the future to allow describing the ports for phy-less devices.
