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.

|
||||
.Sh SYNOPSIS
|
||||
.Cd "device miibus"
|
||||
.Cd "device bge"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides support for various NICs based on the Broadcom BCM570x
|
||||
family of gigabit ethernet controller chips, including the
|
||||
following:
|
||||
.Pp
|
||||
.Bl -bullet -compact
|
||||
.It
|
||||
3Com 3c996-T (10/100/1000baseTX)
|
||||
.It
|
||||
Dell PowerEdge 2550 integrated BCM5700 NIC (10/100/1000baseTX)
|
||||
.It
|
||||
SysKonnect SK-9D21 (10/100/1000baseTX)
|
||||
.It
|
||||
SysKonnect SK-9D41 (1000baseSX)
|
||||
.El
|
||||
.Pp
|
||||
All of these NICs are capable of 10, 100 and 1000Mbps speeds over CAT5
|
||||
copper cable, except for the SysKonnect SK-9D41 which supports only
|
||||
1000Mbps over multimode fiber.
|
||||
The BCM570x builds upon the technology of the Alteon Tigon II. 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
|
||||

|
||||
.Xr ifconfig 8 .
|
||||

|
||||

||||
.It "bge%d: failed to enable memory mapping!"
|
||||
