| 84bus interface. 85This includes most of the adapters which are also supported by the | 85bus Ethernet chip sets supported by the |

| 90driver does not support all features of these adapters however, thus the | 90driver treats all of these 91.Tn PCI 92bus Ethernet chip sets as an 93.Tn AMD Am79C970 PCnet-PCI 94and does not support the additional features like the MII bus and burst mode of 95.Tn AMD Am79C971 PCnet-FAST 96and greater chip sets. 97Thus the |
| 91.Xr pcn 4 | 98.Xr pcn 4 |
| 92driver should be preferred. | 99driver should be preferred for the latter. |
