loader.conf 5 : +.Bd -literal -offset indent +if_sf_load="YES" +.Ed +.Sh DESCRIPTION +The +.Nm +driver provides support for Adaptec Duralink Fast Ethernet adapters +based on the Adaptec AIC-6915 "Starfire" chipset. +.Pp +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. +.Pp +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 +.Nm +driver. +.Pp +The +.Nm +driver supports the following media types: +.Pp +.Bl -tag -width xxxxxxxxxxxxxxxxxxxx +.It autoselect +Enable autoselection of the media type and options. +The user can manually override +the autoselected mode by adding media options to the +.Pa /etc/rc.conf +file. +.It 10baseT/UTP +Set 10Mbps operation. +The +.Ar mediaopt +option can also be used to select either +.Ar full-duplex +or +.Ar half-duplex +modes. +.It 100baseTX +Set 100Mbps (Fast Ethernet) operation. +The +.Ar mediaopt +option can also be used to select either +.Ar full-duplex +or +.Ar half-duplex +modes. +.El +.Pp +The +.Nm +driver supports the following media options: +.Pp +.Bl -tag
