# IOUserNetworkMediaType

A structure describing a specific Ethernet type and configuration that your driver supports.

## Declaration

```occ
typedef uint32_t IOUserNetworkMediaType;
```

## Discussion

Discussion To specify a media type, combine a media type constant with zero or more configuration options. For example, if your driver supports 10-BaseT Ethernet in full duplex mode, use the following code to configure that media type. IOUserNetworkMediaType media_type = kIOUserNetworkMediaEthernet10BaseT | kIOUserNetworkMediaOptionFullDuplex;
