- IBM xSeries 3650 integrated BCM5708 NIC (10/100/1000baseT)
The NetXtreme II product family is composed of various Converged
NIC (or CNIC) Ethernet controllers which support a TCP Offload Engine (TOE),
Remote DMA (RDMA), and iSCSI acceleration, in addition to standard L2
Ethernet traffic, all on the same controller. The following features are
supported in the bnx
driver under
NetBSD:
IPv4 receive IP/TCP/UDP checksum offload Jumbo frames (up to 9022 bytes) VLAN tag insertion Interrupt coalescing 10/100/1000Mbps operation in full-duplex mode 10/100Mbps operation in half-duplex mode
The bnx
driver supports the following
media types:
autoselect
- Enable autoselection of the media type and options. The user can manually override the autoselected mode via ifconfig(8).
10baseT/UTP
- Set 10Mbps operation. The
ifconfig(8)
mediaopt
option can also be used to select eitherfull-duplex
orhalf-duplex
modes. 100baseTX
- Set 100Mbps (Fast Ethernet) operation. The
ifconfig(8)
mediaopt
option can also be used to select eitherfull-duplex
orhalf-duplex
modes. 1000baseTX
- Set 1000baseTX operation over twisted pair. Only
full-duplex
mode is supported. 1000baseSX
- Set 1000Mbps (Gigabit Ethernet) operation. Both
full-duplex
andhalf-duplex
modes are supported. 2500baseSX
- Set 2500Mbps operation. Only
full-duplex
mode is supported.
The bnx
driver supports the following
media options:
full-duplex
- Force full duplex operation.
half-duplex
- Force half duplex operation.
For more information on configuring this device, see ifconfig(8).

HISTORY
The bnx
driver was written by
David Christensen
<davidch@broadcom.com>
in FreeBSD, where it is called
bce
. And it's ported to
OpenBSD by Brad Smith
<brad@openbsd.org>.
It's ported to NetBSD by Quentin Garnier. The
bnx
device driver first appeared in
NetBSD 4.0.
