39 .Nd "Broadcom BCM570x/5714/5721/5750/5751/5752/5789 PCI Gigabit Ethernet adapter driver"
41 To compile this driver into the kernel,
42 place the following lines in your
43 kernel configuration file:
44 .Bd -ragged -offset indent
49 Alternatively, to load the driver as a
50 module at boot time, place the following line in
52 .Bd -literal -offset indent
56 The following tunable is settable from the loader:
57 .Bl -ohang -offset indent
58 .It Va hw.bge.fake_autoneg
59 set to 1 for special handling of the BCM5704 HW (default is 0).
64 driver provides support for various NICs based on the Broadcom BCM570x,
65 5714, 5721, 5750, 5751, 5752 and 5789 families of Gigabit Ethernet
68 All of these NICs are capable of 10, 100 and 1000Mbps speeds over CAT5
69 copper cable, except for the SysKonnect SK-9D41 which supports only
70 1000Mbps over multimode fiber.
71 The BCM570x builds upon the technology of the Alteon Tigon II.
72 It has two R4000 CPU cores and is PCI v2.2 and PCI-X v1.0 compliant.
74 and UDP checksum offload for both receive and transmit,
75 multiple RX and TX DMA rings for QoS applications, rules-based
76 receive filtering, and VLAN tag stripping/insertion as well as
77 a 256-bit multicast hash filter.
78 Additional features may be
79 provided via value-add firmware updates.
80 The BCM570x supports TBI (ten bit interface) and GMII
81 transceivers, which means it can be used with either copper or 1000baseX
83 Note however the device only supports a single
86 Most BCM5700-based cards also use the Broadcom BCM5401 or BCM5411 10/100/1000
87 copper gigabit transceivers,
88 which support autonegotiation of 10, 100 and 1000Mbps modes in
91 The BCM5700, BCM5701, BCM5703, BCM5704, BCM5714 and BCM5780 also support
92 jumbo frames, which can be configured
93 via the interface MTU setting.
94 Selecting an MTU larger than 1500 bytes with the
96 utility configures the adapter to receive and transmit jumbo frames.
97 Using jumbo frames can greatly improve performance for certain tasks,
98 such as file transfers and data streaming.
102 driver supports the following media types:
103 .Bl -tag -width ".Cm 10baseT/UTP"
105 Enable autoselection of the media type and options.
106 The user can manually override
107 the autoselected mode by adding media options to
110 Set 10Mbps operation.
114 option can also be used to select either
120 Set 100Mbps (Fast Ethernet) operation.
124 option can also be used to select either
130 Set 1000baseTX operation over twisted pair.
135 Set 1000Mbps (Gigabit Ethernet) operation.
145 driver supports the following media options:
146 .Bl -tag -width ".Cm full-duplex"
148 Force full duplex operation.
150 Force half duplex operation.
155 driver also supports one special link option for 1000baseTX cards:
156 .Bl -tag -width ".Cm link0"
158 With 1000baseTX cards, establishing a link between two ports requires
159 that one port be configured as a master and the other a slave.
160 With autonegotiation,
161 the master/slave settings will be chosen automatically.
162 However when manually selecting the link state, it is necessary to
163 force one side of the link to be a master and the other a slave.
166 driver configures the ports as slaves by default.
171 will set a port as a master instead.
