26# Driver.conf file for the BGE driver, for
27# Broadcom 579x Gigabit Ethernet devices
28#
29# All the properties below can be set globally (i.e. for all instances
30# of BGE), or on a per-instance basis.  See driver.conf(5) for details
31# of the syntax of global and per-instance properties.
32#
33# Properties specified in this file take effect when the driver is first
34# loaded, typically just after system boot.  Changes to the file will
35# therefore not take effect until the next reboot, but will be permanent
36# thereafter.
37#
38# Some of the driver's parameters can also be changed using ndd(8).
39# Changes made with ndd apply only to a specific instance (e.g. bge1).
40# They take effect immediately, but are lost if the driver is unloaded.

44# The autonegotiation feature can be controlled by the boolean properties
45# listed below.
46#
47# Firstly, 'adv_autoneg_cap' controls whether autonegotiation is enabled.
48#
49# If autonegotiation is turned OFF ("forced mode"), the remaining 'adv_*'
50# speed/duplex properties force selection of a specific mode, namely,
51# the first mode found to be enabled, in highest-to-lowest speed order
52# (thus, if adv_1000fdx_cap=1, all other values will be ignored; to force
53# 10/hdx mode, *all* the faster modes must be explicitly disabled).
54#
55# BEWARE - it's very easy to end up with a non-working link using forced
56# mode.  There's NO validation that the link partner actually supports
57# the mode that this device has been forced into.  In some cases, this
58# will prevent the link coming up; in others, the link status will show
59# 'up' (electrical connection made) but data transfer will not work at
60# all, or will work poorly (low throughput, high collision rates, etc).
61#
62# Note that many switches *require* autonegotiation in order to operate
63# at 1000Mbps or in full-duplex mode or with flow control.  In other words,
64# the only combinations that are likely to work with autonegotiation off
65# are 100Mbps/half-duplex and 10Mbps/half-duplex, unless the peer has also
66# been manually forced to some other (matching) combination.
67#
68# With autonegotiation ON (the default and preferred mode), the 'adv_*'
69# properties control which capabilities are advertised to the partner.
70# The default is to advertise all the capabilities that the hardware
71# supports; thus, the properties below serve only to limit the advertised
72# capabilities to restricted subset -- it is not possible to advertise a
73# capability that the hardware does not support.
74#
75# The autonegotiation process will then automagically select the fastest
76# speed/duplex mode and greatest degree of flow control supported by both
77# partners.
78#
79# If the local device is set to autonegotiate, but the link partner can't
80# or doesn't autonegotiate, the correct speed will be determined anyway,
81# and HALF-DUPLEX mode will be selected, as mandated by the IEEE802.3
82# standard.  This will yield the correct result if the partner is in fact
83# incapable of autonegotiating: it must be a half-duplex device, because
84# the only devices that don't support autonegotation are half-duplex (the
85# standard says that all full-duplex-capable devices must also support
86# autonegotiation).
87#
88# However, this choice will NOT be correct if the peer is actually capable
89# of autonegotiation and full-duplex operation, and has been manually set
90# to "forced full-duplex without autonegotiation" (a mode not recommended
91# by the IEEE standard).  The link will appear to work, but the duplex
92# mismatch will result in packet loss and spurious "late collisions".  In
93# such cases, the preferred solution is to enable autonegotiation by the
94# peer.  Failing that, autonegotiation by the BGE device can be disabled,
95# and forced mode used to match the peer's forced settings as above.

97# adv_autoneg_cap	= 1;

112#
113# OBP's device driver exports methods to set the link speed explicity,
114# which then pass the information to the Solaris driver through the
115# 'transfer-speed' property.  It therefore SHOULDN'T be set here, but
116# is documented for completeness.  If the 'transfer-speed' property is
117# set to 10, 100, or 1000, the link will be set to the selected speed,
118# and autonegotiation ENABLED but restricted to the specified speed.
119# The correct duplex setting will be determined by autonegotiation.
120#
121# This property, if set, overrides and alters the settings of the adv_*
122# parameters corresponding to the properties above.

127#
128# As a third alternative, the following two properties can be set to
129# force the link speed/duplex setting instead.  Doing so will override
130# and alter the settings of the adv_* parameters corresponding to the
131# properties above, and take precedence over all other means of setting
132# the speed/duplex at boot time.
133#
134# Autonegotiation will be DISABLED if EITHER of these properties is set,
135# therefore BOTH properties should be set explicity if either one is.
136# 'speed' may be set to 10, 100 or 1000, while 'full-duplex' may be 0 or 1.
137#
138# See the warning above about the potential for misconfiguration when
139# autonegotiation is disabled.  Defining these properties could leave your
140# system configured so that the network will not work at all after reboot,
141# requiring manual intervention and further reboots to recover!
