QLogic FastLinQ QL45xxx 10/25/40/50/100 Gigabit Ethernet Driver


The qede Ethernet driver is a multi-threaded, loadable, clonable, GLDv3-based driver supporting the Data Link Provider Interface, dlpi(7P), over QLogic FastLinQ QL45xxx 10/25/40/50/100 Gigabit Ethernet controllers. Multiple QLogic FastLinQ controllers installed within the system are supported by the driver.

The qede driver provides support for the QLogic QL45xxx line of devices. Functions include chip initialization, frame transmit and receive, multicast and promiscuous support, error recovery and reporting. These devices provide 10000/25000/40000/50000/100000 Mbps networking interfaces.

The primary methods of configuration are via modification of the /kernel/drv/qede.conf file or execution of the dladm(1M) utility. There are many configuration items available and all are thoroughly documented in the /kernel/drv/qede.conf file. Note that for changes to this file to take affect the driver must be reloaded or the system rebooted. In order to reload the driver with new configuration changes all qede interfaces must be first unplumbed and then the update_drv(1M) tool must be executed. For the configuration items that do not require a driver reload the dladm(1M) tool can be used to dynamically change the option. Use of dladm(1M) is the preferred method.

There are many statistics exposed via kstat(1M) by the qede driver. The main groups are:
for interrupts stats
for layer 2 chip stats
for layer 2 driver stats
for general layer 2 stats
for detailed link status
for GLDv3 MAC layer stats
for Rx ring stats
for Tx ring stats
for general driver stats and version info.

To get a list of all the individual statistics in these groups run:

# kstat -m qede -i 0 -l
