devnp-bcm43xx.so

Driver for the Broadcom-based 43xx 802.11b/g wireless Ethernet controller

Syntax:

io-pkt-variant -d bcm43xx [option[,option ...]] ... &

where variant is one of v4, v4-hc, or v6-hc.

Runs on:

Neutrino

Options:

---

Use commas (,), not spaces, to separate the options.

---

irq=num

The IRQ of the interface. It's automatically detected by default.

mac=XXXXXXXXXXXX

The MAC address of controller. The default is automatically detected on supported hardware.

pio

Run the driver in PIO mode; the default is bus master.

verbose
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.

Description:

The devnp-bcm43xx.so driver controls the Broadcom-based 802.11b/g wireless Ethernet controller. This is a native io-pkt driver; its interface names are in the form bcmX, where X is an integer.

The devnp-bcm43xx.so driver is fully integrated with the 802.11 layer in the stack. It supports both infrastructure client and access point modes of operation. For further information, see ifconfig, wpa_supplicant, and hostapd.

Some devices support hardware checksums, although some might do so in only one direction; to determine if your device does, type:

ifconfig bcmX

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.

Examples:

Start the v6 variant of io-pkt using the Broadcom 43xx driver:

io-pkt-v6-hc -d bcm43xx
