Myson Technology Ethernet PCI driver

## NAME

**my** – Myson Technology Ethernet PCI driver

## SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file:

**device my**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
if_my_load="YES"
```

## DESCRIPTION

The **my** driver provides support for various NICs based on the Myson chipset. The Myson chipset is a variant of the DEC Tulip NIC chipset.

The driver will work with almost any MII-compliant PHY, thus failure to positively identify the chip is not a fatal error.

The **my** driver provides support for various NICs based on the Myson chipset. Supported models include:

- Myson MTD800 PCI Fast Ethernet chip

- Myson MTD803 PCI Fast Ethernet chip

- Myson MTD89X PCI Gigabit Ethernet chip
