DESCRIPTION
The
bnx driver supports Broadcom's NetXtreme II product family, such as the BCM5706 PCI-X and BCM5708-BCM5709 PCI Express Ethernet controllers, which includes the following:
-
Dell PowerEdge 1950 integrated BCM5708 NIC (10/100/1000baseT)
-
Dell PowerEdge 2950 integrated BCM5708 NIC (10/100/1000baseT)
-
Dell PowerEdge M710 integrated BCM5709S NIC (1000baseSX)
-
HP NC370F PCI-X Multifunction Gigabit server adapter (1000baseSX)
-
HP NC370T PCI-X Multifunction Gigabit server adapter (10/100/1000baseT)
-
HP NC373F PCI Express Multifunction Gigabit server adapter (1000baseSX)
-
HP NC373i PCI Express Multifunction Gigabit embedded server adapter (10/100/1000baseT)
-
HP NC380T PCI Express Dual Port Multifunction Gigabit server adapter (10/100/1000baseT)
-
IBM xSeries 3550 integrated BCM5708 NIC (10/100/1000baseT)
-
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 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.
-
1000baseTX
-
Set 1000baseTX operation over twisted pair. Only full-duplex mode is supported.
-
1000baseSX
-
Set 1000Mbps (Gigabit Ethernet) operation. Both full-duplex and half-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.
