qede - QLogic FastLinQ QL45xxx 10/25/40/50/100 Gigabit Ethernet Driver
/dev/qede*
The qede Ethernet driver is a multi-threaded, loadable, clonable, GLDv3-based driver supporting the Data Link Provider Interface, dlpi(4P), 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(8) utility. Many configuration items are available, and all are documented in the /kernel/drv/qede.conf file. Note that for changes to this file to take effect, the driver must be reloaded or the system rebooted. In order to reload the driver with new configuration changes, all qede interfaces must first be unplumbed and then the update_drv(8) tool must be executed. For the configuration items that do not require a driver reload, the dladm(8) tool can be used to dynamically change the option.
Many statistics are exposed by qede via kstat. The following are the primary groups:
Interrupt statistics
Layer 2 chip statistics
Layer 2 driver statistics
General layer 2 statistics
Detailed link status
GLDv3 MAC layer statistics
Rx ring statistics
Tx ring statistics
General driver statistics and version information
To display a list of all the individual statistics in these groups, run the following command:
$ kstat -m qede -i 0 -l
An MDB module exists for qede that offers a much deeper level of debugging information than kstat offers. Depending on how kmdb(1) is initiated, the qede module might or might not be automatically loaded. If the module is not loaded automatically, then do the following to load the module manually:
> ::load /kernel/kmdb/amd64/qede
> ::help qede
