devnp-i80579.so

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.

Runs on:

QNX Neutrino

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.

---

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
