32 .Nd Atheros AR8121/AR8113/AR8114 Gigabit/Fast Ethernet driver
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
51 device driver provides support for Atheros AR8121 PCI Express
52 Gigabit Ethernet controllers and Atheros AR8113/AR8114 PCI
53 Express Fast Ethernet controllers.
55 All LOMs supported by the
57 driver have TCP/UDP/IP checksum offload for both receive and transmit,
58 hardware VLAN tag stripping/insertion features and
59 an interrupt coalescing/moderation
60 mechanism as well as a 64-bit multicast hash filter.
62 The AR8121 also supports Jumbo Frames (up to 8132 bytes),
63 which can be configured via the interface MTU setting.
64 Selecting an MTU larger than 1500 bytes with the
66 utility configures the adapter to receive and transmit Jumbo Frames.
70 driver supports the following media types:
71 .Bl -tag -width ".Cm 10baseT/UTP"
73 Enable autoselection of the media type and options.
74 The user can manually override
75 the autoselected mode by adding media options to
80 Set 100Mbps (Fast Ethernet) operation.
82 Set 1000baseT operation over twisted pair.
87 driver supports the following media options:
88 .Bl -tag -width ".Cm full-duplex"
90 Force full duplex operation.
92 Force half duplex operation.
95 For more information on configuring this device, see
100 device driver provides support for the following Ethernet controllers:
104 Atheros AR8113 PCI Express Fast Ethernet controller
106 Atheros AR8114 PCI Express Fast Ethernet controller
108 Atheros AR8121 PCI Express Gigabit Ethernet controller
111 .\"The following variables are available as both
116 .Bl -tag -width "xxxxxx"
117 .It Va dev.ale.%d.int_rx_mod
118 Maximum amount of time to delay receive interrupt processing in
120 The accepted range is 0 to 130000, the default is 30(30us).
121 Value 0 completely disables the interrupt moderation.
122 .It Va dev.ale.%d.int_tx_mod
123 Maximum amount of time to delay transmit interrupt processing in
125 The accepted range is 0 to 130000, the default is 1000(1ms).
126 Value 0 completely disables the interrupt moderation.
