+.Sh NAME
+.Nm qede
+.Nd QLogic FastLinQ QL45xxx 10/25/40/50/100 Gigabit Ethernet Driver
+.Sh SYNOPSIS
+.Pa /dev/net/qede*
+.Sh DESCRIPTION
+The
+.Nm
+Ethernet driver is a multi-threaded, loadable, clonable, GLDv3-based
+driver supporting the Data Link Provider Interface,
+.Xr 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.
+.Pp
+The
+.Nm
+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.
+.Sh DRIVER CONFIGURATION
+The primary methods of configuration are via modification of the
+.Pa /kernel/drv/qede.conf
+file or execution of the
+.Xr dladm 8
+utility.
+There are many configuration items available and all are thoroughly
+documented in the
+.Pa /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
+.Nm qede
+interfaces must be first unplumbed and then the
+.Xr update_drv 8
+tool must be executed.
+For the configuration items that do not require a driver reload the
+.Xr dladm 8
+tool can be used to dynamically change the option.
+Use of
+.Xr dladm 8
+is the preferred method.
+.Sh DEBUGGING
+.Ss kstat
+There are many statistics exposed via
+.Xr kstat 8
+by the
+.Nm
+driver.
+The main groups are:
+.Bl -tag -width Em
+.It Em intr
+for interrupts stats
+.It Em l2chip
+for layer 2 chip stats
+.It Em l2driver
+for layer 2 driver stats
+.It Em l2stats
+for general layer 2 stats
+.It Em link
+for detailed link status
+.It Em mac
+for GLDv3 MAC layer stats
+.It Em rxq#
+for Rx ring stats
+.It Em txq#
+for Tx ring stats
+.It Em stats
+for general driver stats and version info.
