devnp-bce.so

Driver for Broadcom BCM440x 10/100 Ethernet controllers

Syntax:

io-pkt-variant -d bce ... &

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

Runs on:

Neutrino

Options:

None

Description:

The devnp-bce.so driver manages the Broadcom BCM440x 10/100 Ethernet controllers. This is a ported NetBSD driver; its interface names are in the form bceX, 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 bceX

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/bce0, use if_up -p bce0.

---

Examples:

Start the v4 TCP/IP variant of io-pkt using the devnp-bce.so driver:

io-pkt-v4 -d bce
ifconfig bce0 10.184
