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

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 either full-duplex or half-duplex modes.

100baseTX

Set 100Mbps (Fast Ethernet) operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.

1000baseT

Set 1000baseT operation over twisted pair. Only full-duplex mode is supported.

1000baseSX

Set 1000Mbps (Gigabit Ethernet) operation. Only full-duplex mode is 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).
