bnx
— Broadcom
NetXtreme II 10/100/Gigabit Ethernet device
bnx* at pci?
brgphy* at mii?
The bnx
driver supports Broadcom's
NetXtreme II product family which is made up of the BCM5706, BCM5708,
BCM5709, and BCM5716 Ethernet controller chips. Products using these
controller chips include:
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
OpenBSD:
IPv4 receive IP/TCP/UDP checksum offload IPv4 transmit TCP/UDP checksum offload VLAN tag insertion and stripping 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
10baseT/UTP
mediaopt
option can also be used to select either
full-duplex
or half-duplex
modes.100baseTX
mediaopt
option can also be used to select either
full-duplex
or half-duplex
modes.1000baseT
full-duplex
mode is supported.1000baseSX
full-duplex
mode is supported.2500baseSX
full-duplex
mode is
supported.The bnx
driver supports the following
media options:
full-duplex
half-duplex
For more information on configuring this device, see ifconfig(8).
The adapter needs firmware files to run, which are loaded on demand by the driver when the device is attached:
arp(4), brgphy(4), ifmedia(4), intro(4), netintro(4), pci(4), hostname.if(5), ifconfig(8)
The bnx
device driver first appeared in
OpenBSD 4.0.
