Add device driver support for the Broadcom BCM570x family of gigabit
ethernet controllers. This adds support for the 3Com 3c996-T, the
SysKonnect SK-9D21 and SK-9D41, and the built-in gigE NICs on
Dell PowerEdge 2550 servers. The latter configuration hauls ass:
preliminary measurements show TCP speeds of over 900Mbps using
only normal size frames.
TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.
Still need to fix autonegotiation support for 1000baseSX NICs, but
beyond that, driver is pretty solid.

It has +two R4000 CPU cores and is PCI v2.2 and PCI-X v1.0 compliant. It +supports IP, TCP +and UDP checksum checksum offload for both receive and transmit, +multiple RX and TX DMA rings for QoS applications, rules-based +receive filtering, and VLAN tag stripping/insertion as well as +a 256-bit multicast hash filter. Additional features may be +provided via value-add firmware updates. +The BCM570x supports TBI (ten bit interface) and GMII +transceivers, which means it can be used with either copper of 1000baseX +fiber applications. Note however the device only supports a single +speed in TBI mode. +.Pp +Most cards also use the Broadcom BCM5401 or BCM5411 10/100/1000 +copper gigabit tranceivers, +which support autonegotiation of 10, 100 and 1000mbps modes in +full or half duplex. +.Pp +The BCM5700 also supports jumbo frames, which can be configured +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 +The +.Nm +driver supports the following media types: +.Bl -tag -width 10baseTXUTP +.It Cm autoselect +Enable autoselection of the media type and options. +The user can manually override +the autoselected mode by adding media options to +.Xr rc.conf 5 . +.It Cm 10baseT/UTP +Set 10Mbps operation. +The +.Xr ifconfig 8 +.Ic mediaopt +option can also be used to select either +.Cm full-duplex +or +.Cm half-duplex +modes. +.It Cm 100baseTX +Set 100Mbps (fast ethernet) operation. +The +.Xr ifconfig 8 +.Ic mediaopt +option can also be used to select either +.Cm full-duplex +or +.Cm half-duplex +modes. +.It Cm 1000baseTX +Set 1000baseTX operation over twisted pair. +.Cm full-duplex +and +.Cm half-duplex +modes are supported. +.It Cm 1000baseSX +Set 1000Mbps (gigabit ethernet) operation. +Both +.Cm full-duplex +and +.Cm half-duplex +modes are supported. +.El +.Pp +The +.Nm +driver supports the following media options: +.Bl -tag -width full-duplex +.It Cm full-duplex +Force full duplex operation. +.It Cm half-duplex +Force half duplex operation. +.El +.Pp +The +.Nm +driver also supports one special link option for 1000baseTX cards: +.Bl -tag -width link0 +.It Cm link0 +With 1000baseTX cards, establishing a link between two ports requires +that one port be configured as a master and the other a slave. +With autonegotiation, +the master/slave settings will be chosen automatically. +However when manually selecting the link state, it is necessary to +force one side of the link to be a master and the other a slave. +The +.Nm +driver configures the ports as slaves by default. +Setting the +.Cm link0 +flag with +.Xr ifconfig 8 +will set a port as a master instead. +.El +.Pp +For more information on configuring this device, see +.Xr ifconfig 8 . +.Sh DIAGNOSTICS +.Bl -diag +.It "bge%d: couldn't map memory" +A fatal initialization error has occurred. +.It "bge%d: couldn't map ports" +A fatal initialization error has occurred. +.It "bge%d: couldn't map interrupt" +A fatal initialization error has occurred. +.It "bge%d: no memory for softc struct!" +The driver failed to allocate memory for per-device instance information +during initialization. +.It "bge%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 "bge%d: no memory for jumbo buffers!" +The driver failed to allocate memory for jumbo frames during +initialization. +.It "bge%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 arp 4 , +.Xr netintro 4 , +.Xr ng_ether 4 , +.Xr vlan 4 , +.Xr ifconfig 8 +.Sh HISTORY +The +.Nm +device driver first appeared in +.Fx 5.0 . +.Sh AUTHORS +The +.Nm +driver was written by +.An Bill Paul Aq wpaul@windriver.com . |
