Description:

The Nic_t structure is the main structure used to store nicinfo information. The members include:

ext

A pointer to adapter-specific information.

flags

A combination of the following:

• NIC_FLAG_PIO -- NIC uses PIO Transfers.
• NIC_FLAG_DMA -- NIC uses DMA (8237) Transfers.
• NIC_FLAG_BMSTR -- NIC uses Busmaster Transfers.
• NIC_FLAG_MMAP -- NIC uses Memory Mapped Transfers.
• NIC_FLAG_FDX -- NIC supports full duplex operation.
• NIC_FLAG_BNC -- NIC is using BNC.
• NIC_FLAG_AUI -- NIC is using AUI.
• NIC_FLAG_UTP -- NIC is using UTP.
• NIC_FLAG_FIBRE -- NIC is using FIBRE.
• NIC_FLAG_MULTICAST -- NIC accepts multicast.
• NIC_FLAG_PROMISCUOUS -- NIC accepts all frames.
• NIC_FLAG_BROADCAST -- NIC accepts broadcast frames.

filter

Not currently used.

astate

The adapter state.

media

The type of media, which indicates which member of the union in NetStats_t to use:

• NIC_MEDIA_802_3 -- Ethernet
• NIC_MEDIA_802_5 -- token ring
• NIC_MEDIA_FDDI
• NIC_MEDIA_ATM
• NIC_MEDIA_ARCNET
• NIC_MEDIA_CUSTOM

media_rate

The media rate, in Kbits/second. For example, 10Mbit/second is represented by a media_rate of 10,000.

mtu

The maximum transfer unit.

lan

The LAN number?

node

The physical node ID.

cfg

Configuration information for the device.

phy

The physical layer device -- one of:

• PHY_NOT_INSTALLED
• PHY_INTEL_82553AB -- PHY 100, A or B step.
• PHY_INTEL_82553C -- PHY 100, C step.
• PHY_INTEL_82503 -- 10Mbps.
• PHY_NS_83840 -- 100BASE-TX, C step.
• PHY_SEEQ_80C240 -- 100BASE-T4.
• PHY_SEEQ_80C24 -- 10Mbps.
• PHY_NS_DP83840A

mac_length

The length of the MAC address, in bytes.

permanent_address

The MAC address read from the hardware.

current_address;

The permanent MAC address or the address specified on the command line.

nstats

The network statistics; see NetStats_t.
