Driver for Intel Tolapai 80579 Gigabit Ethernet controllers
Syntax:
io-pkt-variant -d i80579 [option[,option...]] ... &
where variant is one of v4, v4-hc, or
v6-hc.
Options:
- did=X
- Detect only devices with this specific PCI Device ID (e.g., 0x5041, 0x5045, or 0x5049).
- poll
- For debugging only.
Don't use an interrupt; poll Rx instead.
- probe_phy=0|1
- Disable (0) or force (1) periodic PHY probing.
- receive=X
- The number of receive descriptors (the default is 256).
- transmit=X
- The number of transmit descriptors (the default is 256).
- verbose=N
- Set the verbosity level.
The default is zero; a larger value for N yields more output.
The output is sent to
slogger;
invoke
sloginfo
to view it.
Description:
The devnp-i80579.so driver manages the
Intel Tolapai 80579 Gigabit Ethernet controller.
This is a native io-pkt driver;
its interface names are in the form gbeX, 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 gbeX
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/gbe0, use
if_up -p gbe0.
Examples:
Start the v4 TCP/IP variant of io-pkt using the
devnp-i80579.so driver:
io-pkt-v4 -d i80579
ifconfig gbe0 10.1
ping -n 10.2
