| 12 | description: | |
| 13 | Lan966x has 7 interfaces, consisting of 2 copper transceivers(CU), |
| 14 | 3 SERDES6G and 2 RGMII interfaces. Two of the SERDES6G support QSGMII. |
| 15 | Also it has 8 logical Ethernet ports which can be connected to these |
| 16 | interfaces. The Serdes controller will allow to configure these interfaces |
| 17 | and allows to "mux" the interfaces to different ports. |
| 18 | |
| 19 | For simple selection of the interface that is used with a port, the |
| 20 | following macros are defined CU(X), SERDES6G(X), RGMII(X). Where X is a |
| 21 | number that represents the index of that interface type. For example |
| 22 | CU(1) means use interface copper transceivers 1. SERDES6G(2) means use |
| 23 | interface SerDes 2. |
