VTE(4) FreeBSD Kernel Interfaces Manual VTE(4)
NAME vte - Vortex86 RDC R6040 Fast Ethernet driver
SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file:
device miibus device vte
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_vte_load="YES"
DESCRIPTION The vte device driver provides support for RDC R6040 Fast Ethernet controller which is commonly found on Vortex86 System On a Chip (SoC).
The RDC R6040 has integrated 10/100 PHY for 10/100Mbps support in full or half-duplex. The controller supports interrupt moderation mechanism, a 64-bit multicast hash filter, VLAN over-size frame and four station addresses. The vte device driver uses three station addresses out of four as perfect multicast filter.
The vte 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.
The vte 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 vte device driver provides support for the following Ethernet controllers:
o DM&P Vortex86 RDC R6040 Fast Ethernet controller
LOADER TUNABLES Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.vte.tx_deep_copy The RDC R6040 controller has no auto-padding support for short frames and the controller's DMA engine does not have capability to handle multiple buffers for a TX frame such that driver has to
SYSCTL VARIABLES The following variables are available as both sysctl(8) variables and loader(8) tunables:
dev.vte.%d.rx_mod Maximum number of packets to fire RX completion interrupt. The accepted range is 0 to 15, the default is 15.
dev.vte.%d.tx_mod Maximum number of packets to fire TX completion interrupt. The accepted range is 0 to 15, the default is 15.
dev.vte.%d.stats Show hardware MAC statistics maintained in driver.
