# ice(4)

Intel Ethernet 800 series PCI Express 1Gb/10Gb/25Gb/50Gb/100Gb Ethernet device

## NAME

**ice** – Intel Ethernet 800 series PCI Express 1Gb/10Gb/25Gb/50Gb/100Gb Ethernet device

## SYNOPSIS

**ice\* at pci?**

## DESCRIPTION

The **ice** driver supports Intel 800 series controllers based on the Intel E810 and E823 Ethernet chipsets, including the following:

- Intel E810-C SFP/QSFP

- Intel E810-XXV SFP/QSFP

- Intel E823-L SFP/QSFP

- Intel E823-L 10G/1G

## FILES

Intel 800 series controllers contain basic firmware which allows the device to be used with single Tx/Rx queues and without any hardware offloading features enabled. For full functionality, the device needs the following firmware file, which is loaded by the driver when the system boots:

- */etc/firmware/ice-ddp*

  This firmware file is not free because Intel refuses to grant distribution rights without contractual obligations. As a result, even though OpenBSD includes the driver, the firmware file cannot be included and users have to download the file on their own.

A prepackaged version of the firmware can be installed using [fw\_update(8)](/fw_update/8.md).

## HISTORY

The **ice** driver first appeared in FreeBSD 12.2. OpenBSD support was added in OpenBSD 7.7.

## AUTHORS

The **ice** driver was written by Intel and ported to OpenBSD by Stefan Sperling ⟨*stsp@openbsd.org*⟩.
