bnxe - QLogic NetXtreme II 10 Gigabit Ethernet Device Driver
The bnxe Ethernet driver is a multi-threaded, loadable, clonable,
GLDv3-based driver supporting the Data Link Provider Interface,
dlpi(7P), over QLogic NetXtreme II 10 Gigabit Ethernet controllers.
Multiple NetXtreme II controllers installed within the system are supported by
The bnxe driver provides support for the NetXtreme II 10
Gigabit line of devices. Functions include chip initialization, frame
transmit and receive, multicast and promiscuous support, error recovery and
reporting. These devices provide 10/100/1000/2500/10000 Mbps networking
The primary methods of configuration are via modification of the
/kernel/drv/bnxe.conf file or execution of the dladm(1M)
utility. There are many configuration items available and all are thoroughly
documented in the /kernel/drv/bnxe.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 bnxe
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.
There are many statistics exposed via kstat by bnxe.
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, and
- for general driver stats and version info.
To get a list of all the individual statistics in these groups
run: % kstat -m bnxe -i 0 -l
