DESCRIPTION

• ANA-62011 64-bit single port 10/100baseTX
• ANA-62022 64-bit dual port 10/100baseTX
• ANA-62044 64-bit quad port 10/100baseTX

The AIC-6915 is a bus master controller with an MII interface. It supports high and low priority transmit and receive queues, TCP/IP checksum offload, multiple DMA descriptor formats and both polling and producer/consumer DMA models. The AIC-6915 receive filtering options include a 16 entry perfect filter, a 512-bit hash table for multicast addresses, a 512-bit hash table for priority address matching and VLAN filtering. An external MII-compliant transceiver is required for media interfacing.

Multiport adapters consist of several AIC-6915 controllers connected via a PCI to PCI bridge. Each controller is treated as a separate interface by the sf driver.

The sf driver supports the following media types:

autoselect

Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the hostname.if(5) file.

10baseT

Set 10Mbps operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

100baseTX

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

The sf 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).
