Robin H. Johnson b264931034 doc/net.example: Add warnings that changing MAC on bonds can break things.
In most cases, changing the MAC on a bond manually is wrong. The bonding
module will do it as needed to failover between interfaces, or to get
multiple interfaces to correctly have the same MAC.

We cannot however enforce it, as there are some corner cases where it is
actually valid (hardware that requires specific MAC configuration, like
some quad-port NICs).

# QUICK-START
#
# The quickest start is if you want to use DHCP.
# In that case, everything should work out of the box, no configuration
# necessary, though the startup script will warn you that you haven't
# specified anything.
# WARNING :- some examples have a mixture of IPv4 (ie 192.168.0.1) and IPv6
# (ie 4321:0:1:2:3:4:567:89ab) internet addresses. They only work if you have
# the relevant kernel option enabled. So if you don't have an IPv6 enabled
# kernel then remove the IPv6 address from your config.
# If you want to use a static address or use DHCP explicitly, jump
# down to the section labeled INTERFACE HANDLERS.
#
# If you want to do anything more fancy, you should take the time to
# read through the rest of this file.
##############################################################################
# MODULES
#
# We now support modular networking scripts which means we can easily
# add support for new interface types and modules while keeping
# compatibility with existing ones.
#
# Modules load by default if the package they need is installed. If
# you specify a module here that doesn't have its package installed
# then you get an error stating which package you need to install.
# Ideally, you only use the modules setting when you have two or more
# packages installed that supply the same service.
#
# In other words, you probably should DO NOTHING HERE...
# Prefer ifconfig over iproute2
#modules="ifconfig"
# You can also specify other modules for an interface
# In this case we prefer udhcpc over dhcpcd
#modules_eth0="udhcpc"
# You can also specify which modules not to use - for example you may be
# using a supplicant or linux-wlan-ng to control wireless configuration but
# you still want to configure network settings per SSID associated with.
#modules="!iwconfig !wpa_supplicant"
# IMPORTANT: If you need the above, please disable modules in that order
##############################################################################
# INTERFACE HANDLERS
#
# We provide two interface handlers presently: ifconfig and iproute2.
# You need one of these to do any kind of network configuration.
# For ifconfig support, emerge sys-apps/net-tools
# For iproute2 support, emerge sys-apps/iproute2
# If you don't specify an interface then we prefer iproute2 if it's installed
# To prefer ifconfig over iproute2
#modules="ifconfig"
# For a static configuration, use something like this
# (They all do exactly the same thing btw)
#config_eth0="192.168.0.2/24"
#config_eth0="192.168.0.2 netmask 255.255.255.0"
# If you need more than one address, you can use something like this
# NOTE: ifconfig creates an aliased device for each extra IPv4 address
# (eth0:1, eth0:2, etc)
# iproute2 does not do this as there is no need to
# WARNING: You cannot mix multiple addresses on a line with other parameters!
#config_eth0="192.168.0.2/24 192.168.0.3/24 192.168.0.4/24"
# However, that only works with CIDR addresses, so you can't use netmask.
# You can also use IPv6 addresses
# (you should always specify a prefix length with IPv6 here)
#config_eth0="192.168.0.2/24 4321:0:1:2:3:4:567:89ab/64 4321:0:1:2:3:4:567:89ac/64"
# If you wish to keep existing addresses + routing and the interface is up,
# you can specify a noop (no operation). If the interface is down or there
# are no addresses assigned, then we move onto the next step (default dhcp)
# This is useful when configuring your interface with a kernel command line
# or similar
#config_eth0="noop 192.168.0.2/24"
# If you don't want ANY address (only useful when calling for advanced stuff)
#config_eth0="null"
# If you need to pass parameters to go with an address, you can do so on the
# same line as the address. You should split multiple addresses with newlines.
# WARNING: You cannot mix multiple addresses on a line with other parameters!

# If a specified module fails (like dhcp - see below), you can specify a
# fallback like so
#fallback_eth0="192.168.0.2/24"
#fallback_routes_eth0="default via 192.168.0.1"
# NOTE: fallback entry must match the entry location in config_eth0
# As such you can only have one fallback route.
# Also, if you do not set a fallback_routes entry for an interface, the
# routes entry will be used if that is set.
# Some users may need to alter the MTU - here's how
#mtu_eth0="1500"
# Same for TX Queue Length
#txqueuelen_eth0="1000"
# Each module described below can set a default base metric, lower is
# preferred over higher. This is so we can prefer a wired route over a
# wireless route automatically. You can override this by setting
#metric_eth0="100"
# or on a global basis
#metric="100"
# The only downside of the global setting is that you have to ensure that
# there are no conflicting routes yourself. For users with large routing
# tables you may have to set a global metric as the due to a simple read of
# the routing table taking over a minute at a time.
# You may wish to disable the interface being brought down when stopping.
# This is only of use for WakeOnLan.

###############################################
# SETTINGS
# Hard code an SSID to an interface - leave this unset if you wish the driver
# to scan for available Access Points
# Set to "any" to connect to any SSID - the driver picks an Access Point
# This needs to be done when the driver doesn't support scanning
# This may work for drivers that don't support scanning but you need automatic
# AP association
# I would only set this as a last resort really - use the preferred_aps
# setting at the bottom of this file
# However, using ad-hoc (without scanning for APs) and master mode
# do require the SSID to be set - do this here
#essid_eth0="any"
# Set the mode of the interface (managed, ad-hoc, master or auto)
# The default is auto
# If it's ad-hoc or master you also may need to specify the channel below

# If managed mode fails, drop to ad-hoc mode with the below SSID?
#adhoc_essid_eth0="WLAN"
# Some drivers/hardware don't scan all that well. We have no control over this
# but we can say how many scans we want to do to try and get a better sweep of
# the area. The default is 1.
#scans_eth0="1"
#Channel can be set (1-14), but defaults to 3 if not set.
#
# The below is taken verbatim from the BSD wavelan documentation found at
# http://www.netbsd.org/Documentation/network/wavelan.html
# There are 14 channels possible; We are told that channels 1-11 are legal for
# North America, channels 1-13 for most of Europe, channels 10-13 for France,
# and only channel 14 for Japan. If in doubt, please refer to the documentation
# that came with your card or access point. Make sure that the channel you
# select is the same channel your access point (or the other card in an ad-hoc
# network) is on. The default for cards sold in North America and most of Europe
# is 3; the default for cards sold in France is 11, and the default for cards
# sold in Japan is 14.

# don't report properly either.
# So if you have connection problems try flipping this setting

# DHCP can be provided by dhclient, dhcpcd, pump or udhcpc.

# pump: emerge net-misc/pump
# udhcpc: emerge sys-apps/busybox
# If you have more than one DHCP client installed, you need to specify which
# one to use - otherwise we default to dhcpcd if available.
#modules="dhclient" # to select dhclient over dhcpcd
#
# Notes:
# - All clients send the current hostname to the DHCP server by default
# - dhcpcd does not daemonize when the lease time is infinite
# - udhcp-0.9.3-r3 and earlier do not support getting NTP servers
# - pump does not support getting NIS servers
# - DHCP tends to erase any existing device information - so add
# static addresses after dhcp if you need them
# - dhclient and udhcpc can set other resolv.conf options such as "option"
# and "sortlist"- see the System module for more details
# Regardless of which DHCP client you prefer, you configure them the
# same way using one of following depending on which interface modules
# you're using.

# You can pass options to them in a similar manner to dhcpcd though

# GENERIC DHCP OPTIONS
# Set generic DHCP options like so
#dhcp_eth0="release nodns nontp nonis nogateway nosendhost"
# This tells the dhcp client to release its lease when it stops, not to
# overwrite dns, ntp and nis settings, not to set a default route and not to
# send the current hostname to the dhcp server and when it starts.
# You can use any combination of the above options - the default is not to
# use any of them.

# Advanced Routing
# WARNING: For advanced routing you MUST be using sys-apps/iproute2

# This provides a means to do multi-homing and more using the Routing Policy
# Database (RPDB).
#
# See the following links for background and more information.
# http://linux-ip.net/html/ch-routing.html
# http://linux-ip.net/html/ch-advanced-routing.html
# The rules listed will be added with 'ip rule add LINE' when the interface is
# being brought up. They will also be removed with 'ip rule delete LINE'.
# The rules added are also stored for later removal, so if you alter your rules
# directly before stopping, you should review your rules again after stopping.
# Note in earlier versions of openrc, this was provided as an example in
# postup/postdown, however that implementation suffered some bugs in corner
# cases, which are now fixed with this merger. If you used the previous
# example, you should only need to drop the relevent portions of your
# postup/postdown functions, and review the quoting in your rules_IFACE
# variables.
# Below is a trivial example for a dual-homed connection where there is an OOB
# management network. Only packets explicitly with an address from or to the
# OOB are sent via eth0. All others go via eth1 as the eth1 rules have a lower
# priority.
# If you want to use names for your tables, you should put lines into
# /etc/iproute2/rt_tables, an example follows:
# 2 oob
# 3 external
#
# IPv6 RPDB entries are to be found in the rules6_IFVAR variables:
#rules_eth0="
#from ZZZ.ZZZ.200.128/27 table oob priority 500
#to ZZZ.ZZZ.200.128/27 table oob priority 550"
#rules_eth1="
#from XXX.XXX.112.0/24 table external priority 400
#to XXX.XXX.112.0/24 table external priority 450"
#routes_eth0="
#ZZZ.ZZZ.200.128/27 dev eth0 table oob scope link
#default via ZZZ.ZZZ.200.129 table oob"
#routes_eth1="
#XXX.XXX.112.0/24 dev eth1 table external scope link
#default via XXX.XXX.112.1 dev eth1"
