# NAME

`myx` — Myricom Myri-10G PCI Express 10Gb Ethernet device

# SYNOPSIS

`myx* at pci?`

# DESCRIPTION

The `myx` driver supports the Myricom Myri-10G PCI Express 10Gb Ethernet adapters based on the Myricom Lanai-Z8E and Lanai-Z8ES chipsets, including the following:

- Myricom 10G-PCIE-8A-C Adapter (10GbaseCX4)
- Myricom 10G-PCIE-8A-R Adapter (10GbaseSR/LR)
- Myricom 10G-PCIE-8A-Q Adapter (10G XAUI)

# FILES

The adapter needs a firmware file, which is selected and loaded on demand by the driver when the device is attached:

/etc/firmware/myx-eth_z8e
/etc/firmware/myx-ethp_z8e

# SEE ALSO

arp(4), ifmedia(4), intro(4), netintro(4), pci(4), hostname.if(5), ifconfig(8)

# HISTORY

The `myx` driver first appeared in OpenBSD 4.2.

# AUTHORS

The `myx` driver was written by Reyk Floeter <reyk@openbsd.org>.

# CAVEATS

While the firmware supports reading module information for ifconfig(8) `transceiver` to use, it does not support writing to the module. This prevents configuration of the module, which may prevent ifconfig(8) from reading the right data from the module where other network cards succeed.
