NAME
     ale — Atheros AR8121/AR8113/AR8114 Gigabit/Fast Ethernet driver

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

	   device miibus
	   device ale

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

	   if_ale_load="YES"

DESCRIPTION
     The ale device driver provides support for Atheros AR8121 PCI Express
     Gigabit Ethernet controllers and Atheros AR8113/AR8114 PCI Express Fast
     Ethernet controllers.

     All LOMs supported by the ale driver have TCP/UDP/IP checksum offload for
     both receive and transmit, TCP segmentation offload (TSO), hardware VLAN
     tag stripping/insertion features, Wake On Lan (WOL) and an interrupt coa‐
     lescing/moderation mechanism as well as a 64-bit multicast hash filter.

     The AR8121 also supports Jumbo Frames (up to 8132 bytes), which can be
     configured 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 ale driver supports the following media types:

     autoselect	  Enable autoselection of the media type and options.  The
		  user can manually override the autoselected mode by adding
		  media options to rc.conf(5).

     10baseT/UTP  Set 10Mbps operation.

     100baseTX	  Set 100Mbps (Fast Ethernet) operation.

     1000baseTX	  Set 1000baseTX operation over twisted pair.

     The ale driver supports the following media options:

     full-duplex  Force full duplex operation.

     half-duplex  Force half duplex operation.

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

HARDWARE
     The ale device driver provides support for the following Ethernet con‐
     trollers:

     ·	 Atheros AR8113 PCI Express Fast Ethernet controller
     ·	 Atheros AR8114 PCI Express Fast Ethernet controller
     ·	 Atheros AR8121 PCI Express Gigabit Ethernet controller

LOADER TUNABLES
     Tunables can be set at the loader(8) prompt before booting the kernel or
     stored in loader.conf(5).

     hw.ale.msi_disable
	     This tunable disables MSI support on the Ethernet hardware.  The
	     default value is 0.

     hw.ale.msix_disable
	     This tunable disables MSI-X support on the Ethernet hardware.
	     The default value is 0.

SYSCTL VARIABLES
     The following variables are available as both sysctl(8) variables and
     loader(8) tunables:

     dev.ale.%d.int_rx_mod
	     Maximum amount of time to delay receive interrupt processing in
	     units of 1us.  The accepted range is 0 to 130000, the default is
	     30(30us).	Value 0 completely disables the interrupt moderation.

     dev.ale.%d.int_tx_mod
	     Maximum amount of time to delay transmit interrupt processing in
	     units of 1us.  The accepted range is 0 to 130000, the default is
	     1000(1ms).	 Value 0 completely disables the interrupt moderation.

     dev.ale.%d.process_limit
	     Maximum amount of Rx frames to be processed in the event loop
	     before rescheduling a taskqueue.  The accepted range is 32 to
	     255, the default value is 128 events.  The interface does not
	     need to be brought down and up again before a change takes
	     effect.

HISTORY
     The ale driver was written by Pyun YongHyeon ⟨yongari@FreeBSD.org⟩.  It
     first appeared in FreeBSD 7.1.
