NAME

ice — Intel Ethernet 800 Series Driver

SYNOPSIS

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

device iflib
device ice

To load the driver as a module at boot time, place the following lines in loader.conf(5):

if_ice_load="YES"

DESCRIPTION

Features

The ice driver provides support for any PCI Express adapter or LOM (LAN On Motherboard) in the Intel Ethernet 800 Series. As of this writing, the series includes devices with these model numbers:

Intel® Ethernet Controller E810-C
Intel® Ethernet Controller E810-XXV
Intel® Ethernet Connection E822-C
Intel® Ethernet Connection E822-L
Intel® Ethernet Connection E823-C
Intel® Ethernet Connection E823-L

For questions related to hardware requirements, refer to the documentation supplied with your adapter.

Support for Jumbo Frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility configures the adapter to receive and transmit Jumbo Frames. The maximum MTU size for Jumbo Frames is 9706. This value coincides with the maximum Jumbo Frame size of 9728.

This driver version supports VLANs. For information on enabling VLANs, see the README.

Offloads are also controlled via the interface, for instance, checksumming for both IPv4 and IPv6 can be set and unset, TSO4 and/or TSO6, and finally LRO can be set and unset.

For more information on configuring this device, see ifconfig(8).

Additional Utilities

There are additional tools available from Intel to help configure and update the adapters covered by this driver. These tools can be downloaded directly from Intel at https://downloadcenter.intel.com, by searching for their names, or by installing certain packages:

To change the behavior of the QSFP28 ports on E810-C adapters, use the Intel EPCT (Ethernet Port configuration tool); installed by the sysutils/intel-epct package.
To update the firmware on an adapter, use the Intel Non-Volatile Memory (NVM) Update Utility for Intel Network Adapter 800 series; installed by the sysutils/intel-nvmupdate-100g package.

HARDWARE

The ice driver supports the Intel Ethernet 800 series. Most adapters in this series with SFP28/QSFP28 cages have firmware that requires that Intel qualified modules are used; these qualified modules are listed below. This qualification check cannot be disabled by the driver.

The ice driver supports 100Gb Ethernet adapters with these QSFP28 modules:

Intel® 100G QSFP28 100GBASE-SR4 E100GQSFPSR28SRX
Intel® 100G QSFP28 100GBASE-SR4 SPTMBP1PMCDF
Intel® 100G QSFP28 100GBASE-CWDM4 SPTSBP3CLCCO
Intel® 100G QSFP28 100GBASE-DR SPTSLP2SLCDF

The ice driver supports 25Gb and 10Gb Ethernet adapters with these SFP28 modules:

Intel® 10G/25G SFP28 25GBASE-SR E25GSFP28SR
Intel® 25G SFP28 25GBASE-SR E25GSFP28SRX (Extended Temp)
Intel® 25G SFP28 25GBASE-LR E25GSFP28LRX (Extended Temp)

The ice driver supports 10Gb and 1Gb Ethernet adapters with these SFP+ modules:

Intel® 1G/10G SFP+ 10GBASE-SR E10GSFPSR
Intel® 1G/10G SFP+ 10GBASE-SR E10GSFPSRG1P5
Intel® 1G/10G SFP+ 10GBASE-SR E10GSFPSRG2P5
Intel® 10G SFP+ 10GBASE-SR E10GSFPSRX (Extended Temp)
Intel® 1G/10G SFP+ 10GBASE-LR E10GSFPLR

Note that adapters also support all passive and active limiting direct attach cables that comply with SFF-8431 v4.1 and SFF-8472 v10.4 specifications.

This is not an exhaustive list; please consult product documentation for an up-to-date list of supported media.

LOADER TUNABLES

Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5). See the iflib(4) man page for more information on using iflib sysctl variables as tunables.

hw.ice.#.enable_health_events: TBW
hw.ice.#.debug.enable_tx_fc_filter: TBW
hw.ice.#.debug.enable_tx_lldp_filter: TBW
hw.ice.#.debug.enable_health_events: TBW

SYSCTL PROCEDURES

dev.ice.#.fc: Allows one to set the flow control value. A value of 0 disables flow control, 3 enables full, 1 is RX, and 2 is TX pause.
dev.ice.#.advertise_speed: Allows one to set advertised link speeds, this will then cause a link renegotiation.
dev.ice.#.current_speed: This is a display of the current setting.
dev.ice.#.fw_version: Displays the current firmware and NVM versions of the adapter.
dev.ice.#.ddp_version: TBW
dev.ice.#.requested_fec: TBW
dev.ice.#.negotiated_fec: TBW
dev.ice.#.fw_lldp_agent: TBW
dev.ice.#.ets_min_rate: TBW
dev.ice.#.up2tc_map: TBW
dev.ice.#.pfc: TBW

INTERRUPT STORMS

It is important to note that 100G operation can generate high numbers of interrupts, often incorrectly being interpreted as a storm condition in the kernel. It is suggested that this be resolved by setting hw.intr_storm_threshold to 0.
