Driver for Intel 10 Gigabit Ethernet controllers
Syntax:
io-pkt-variant -d ixgbe [option[,option ...]] ... &
where variant is one of v4, v4-hc, or
v6-hc.
Options:
Note:
Use commas, not spaces, to separate the options.
- did=0xXXXX
- Detect only devices with this specific PCI Device ID.
The default is automatically detected on supported hardware.
- duplex=0|1
- Half (0) or full (1) duplex mode. The default is automatically
detected on supported hardware.
If you specify duplex, specify speed as well;
if duplex alone is specified, it is ignored and both speed and duplex
are auto-negotiated.
You can also use ifconfig -m and
ifconfig ixX media to set this.
- force_link
- Force the link speed/duplex.
The default is to autonegotiate the advertised speed/duplex.
- irq=N
- The IRQ of the interface.
The default is automatically detected on supported hardware.
- mac=XXXXXXXXXXXX
- The MAC address of the controller.
The default is automatically detected on supported hardware.
- mtu=N
- The maximum transmission unit.
The default is 1514.
- nomulticast
- Disable the driver from sending or receiving multicast packets.
By default, multicast is enabled.
- pauseignore
- Ignore pause frames with respect to full duplex flow control.
- pausesuppress
- Suppress pause frames with respect to full duplex flow control.
- pci=0xXXXX
- Detect only devices at this specific PCI index.
- priority=N
- The priority of the driver's event-handler thread (default 21).
- promiscuous
- Enable the reception of all packets.
- receive=num
- The number of receive descriptors; the default is 512, and the maximum is 4096.
- speed=N
- Set the link speed (specified in Mbits/second).
- transmit=N
- The number of transmit descriptors; the default is 4096, as is the maximum.
- tx_reap=N
- The maximum number of transmit descriptors to reap.
The default is 64.
- verbose or verbose=num
- Be verbose.
Specify num for more verbosity (num can be 1-4;
the higher the number, the more detailed the output).
The output goes to
slogger;
invoke
sloginfo
to view it.
- vid=0xXXXX
- Detect only devices with this specific PCI Vendor ID.
Description:
The devnp-ixgbe.so driver manages Intel 10 Gigabit Ethernet controllers.
This is a native io-pkt driver;
its interface names are in the form ixX, where
X is an integer.
Some devices support hardware checksums, although some might do so in
only one direction; to determine if your device does, type:
ifconfig ixX
and look for the following in the list of supported options:
- ip4csum, ip4csum-rx, ip4csum-tx
- tcp4csum, tcp4csum-rx, tcp4csum-tx
- tcp6csum, tcp6csum-rx, tcp6csum-tx
- udp4csum, udp4csum-rx, udp4csum-tx
- udp6csum, udp6csum-rx, udp6csum-tx
You can then use
ifconfig
to enable or disable whichever of these options your device supports.
Note:
Native
io-pkt and ported NetBSD drivers don't put entries
into the
/dev/io-net namespace, so a
waitfor
command for such an entry won't work properly in buildfiles or scripts.
Use
if_up -p
instead; for example, instead of
waitfor /dev/io-net/ix0, use
if_up -p ix0.
Examples:
Start io-pkt using the devnp-ixgbe.so driver:
io-pkt-v4 -d ixgbe
ifconfig ix0 192.168.0.10
