XMAC II Gigabit MAC +.Pq Nm sk +and the SysKonnect GEnesis controller ASIC +.Pq Nm skc . +The XMAC provides the Gigabit MAC and PHY support +while the GEnesis provides an interface to the PCI bus, DMA support, +packet buffering and arbitration. +The GEnesis can control up to two XMACs simultaneously, +allowing dual-port NIC configurations. +.Pp +The Marvell based adapters are a single integrated circuit, but are +still presented as a separate MAC +.Pq Nm sk +and controller ASIC +.Pq Nm skc . +At this time, there are no dual-port Marvell based NICs. +.Pp +The +.Nm +driver configures dual port SysKonnect adapters such that each XMAC +is treated as a separate logical network interface. +Both ports can operate independently of each other and can be connected +to separate networks. +The SysKonnect driver software currently only uses the second port on +dual port adapters for failover purposes: if the link +on the primary port fails, the SysKonnect driver will automatically +switch traffic onto the second port. +.Pp +The XaQti XMAC II supports full and half duplex operation with +autonegotiation. +The XMAC also supports unlimited frame sizes. +Support for jumbo frames is provided via the interface MTU setting. +Selecting an MTU larger than 1500 bytes with the +.Xr ifconfig 8 +utility configures the adapter to receive and transmit jumbo frames. +Using jumbo frames can greatly improve performance for certain tasks, +such as file transfers and data streaming. +.Pp +Hardware TCP/IP checksum offloading for IPv4 is available but not +supported by the driver. +.Pp +The following media types and options (as given to +.Xr ifconfig 8 ) +are supported: +.Bl -tag -width xxx -offset indent +.It Cm media No autoselect +Enable autoselection of the media type and options. +The user can manually override +the autoselected mode. +.\" by adding media options to the appropriate +.Xr ifconfig.if 5 +.\" file. +.It Cm media No 1000baseSX Cm mediaopt No full-duplex +Set 1000Mbps (Gigabit Ethernet) operation on fiber and force full-duplex mode. +.It Cm media No 1000baseSX Cm mediaopt No half-duplex +Set 1000Mbps (Gigabit Ethernet) operation on fiber and force half-duplex mode. +.It Cm media No 1000baseT Cm mediaopt No full-duplex +Set 1000Mbps (Gigabit Ethernet) operation and force full-duplex mode. +.El +.Pp +For more information on configuring this device, see +.Xr ifconfig 8 . +To view a list of media types and options supported by the card, try +.Ic ifconfig Fl m Aq Mt device . +For example, +.Ic ifconfig Fl m Ar sk0 . +.Sh DIAGNOSTICS +.Bl -diag +.It "sk%d: couldn't map memory" +A fatal initialization error has occurred. +.It "sk%d: couldn't map ports" +A fatal initialization error has occurred. +.It "sk%d: couldn't map interrupt" +A fatal initialization error has occurred. +.It "sk%d: failed to enable memory mapping!" +The driver failed to initialize PCI shared memory mapping. +This might happen if the card is not in a bus-master slot. +.It "sk%d: no memory for jumbo buffers!" +The driver failed to allocate memory for jumbo frames during +initialization. +.It "sk%d: watchdog timeout" +The device has stopped responding to the network, or there is a problem with +the network connection (cable). +.El +.Sh SEE ALSO +.Xr ifmedia 4 , +.Xr intro 4 , +.Xr netintro 4 , +.Xr pci 4 , +.Xr ifconfig.if 5 , +.Xr ifconfig 8 +.Rs +.%T XaQti XMAC II datasheet +.%U http://www.xaqti.com +.Re +.Rs +.%T SysKonnect GEnesis programming manual +.%U http://www.syskonnect.com +.Re +.Sh HISTORY +The +.Nm +device driver first appeared in +.Fx 3.0 . +.Ox +support was added in +.Ox 2.6 . +.Nx +support was added in +.Nx 2.0 . +.Pp +The +.Nm msk +driver first appeared in +.Ox 4.0 , +and was ported to +.Nx 4.0 . +.Sh AUTHORS +.An -nosplit +The +.Nm +driver was written by +.An Bill Paul Aq Mt wpaul@ctr.columbia.edu . +Support for the Marvell Yukon-2 was added by +.An Mark Kettenis Aq Mt kettenis@openbsd.org . +.Sh BUGS +Support for checksum offload is unimplemented. +Particularly for Yukon-II hardware, there are multiple different +receive and transmit offload silicon bugs which have to be worked +around in software when using hardware offloading. +For this reason, support for hardware offloading +is not very desirable for these controllers, and unlikely to be +ever implemented. +.Pp +Performance with at least some Marvell-based adapters is poor, +especially on loaded PCI buses or when the adapters are behind +PCI-PCI bridges. +It is believed that this is because the Marvell parts have +significantly less buffering than the original SysKonnect cards +had. |
