age -- Attansic/Atheros L1 Gigabit Ethernet driver
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
The age device driver provides support for Attansic/Atheros L1 PCI
Express Gigabit Ethernet controllers.
All LOMs supported by the age driver have TCP/UDP/IP checksum offload for
both transmit and receive, TCP segmentation offload (TSO), hardware VLAN
tag stripping/insertion features and an interrupt moderation mechanism as
well as a 64-bit multicast hash filter.
The L1 also supports Jumbo Frames (up to 10240 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 age 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 age 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).
The age driver provides support for LOMs based on Attansic/Atheros L1
Gigabit Ethernet controller chips, including:
+o ASUS M2N8-VMX
+o ASUS M2V
+o ASUS M3A
+o ASUS P2-M2A590G
+o ASUS P5B-E
+o ASUS P5B-MX/WIFI-AP
+o ASUS P5B-VMSE
+o ASUS P5K
+o ASUS P5KC
+o ASUS P5KPL-C
+o ASUS P5KPL-VM
+o ASUS P5K-SE
+o ASUS P5K-V
+o ASUS P5L-MX
+o ASUS P5DL2-VM
+o ASUS P5L-VM 1394
+o ASUS G2S
Tunables can be set at the loader(8) prompt before booting the kernel or
stored in loader.conf(5).
This tunable disables MSI support on the Ethernet hardware. The
default value is 0.
This tunable disables MSI-X support on the Ethernet hardware.
The default value is 0.
The following variables are available as both sysctl(8) variables and
Maximum amount of time to delay interrupt processing in units of
2us. The accepted range is 0 to 65000, the default is 50
(100us). Value 0 completely disables the interrupt moderation.
Maximum amount of Rx events to be processed in the event loop
before rescheduling a taskqueue. The accepted range is 30 to
255, the default value is 128 events. The interface does not
need to be brought down and up again before a change takes
Display lots of useful MAC counters maintained in the driver.
