This setting, already in use in newnet, allows the user to control
whether network interfaces are stopped when the system shuts down. By
default, under newnet, they are not, so I am making oldnet have the same
default.
A side-affect of this is that in the default configuration this fixes
bugs like the one below.

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).

The newer bonding code using sysfs does not clearly show the most common

Also include a path to the referenced kernel documentation for the other

The network script had a separate case for handling network interface
dependencies using variables of the form
rc_before/after/use/need/provide_ifname. This is unnecessary since
openrc already supports rc_net_ifname_need/use/before/after/provide.
This commit updates the documentation to use this more generally
supported form.
In the case of a single line of configuration, where the address has
parameters, the parameters were being treated as seperate addresses.
Eg:
config_eth0="4321:0:1:2:3:4:567:89ab/64 nodad home preferred_lft 0"
Also document usage of parameters in the net example, and note that
multiple addresses on a single line cannot be mixed with parameters.
Newlines are required to seperate the addresses.

Historically, we have tried to up interfaces before running preup, so
that the kernel setups up the device and makes things like ethtool work
(some hardware cannot be correct probed until then). However this ends
up breaking other hardware, so a variable has been introduced to allow
the up prior to preup to be disabled: up_before_preup_IFVAR=no

The example of how to configure the bridge was invalid. It showed
invalid timer settings along with turning off stp. This update shows how
to turn on stp and set the timer settings to the defaults.

Some variable references were written as $(foo), but the majority were
written as ${foo}. This commit changes all of the variable references
to using braces.
The tree contained many operating system specific Makefiles which were
being included in other Makefiles. This commit removes those and adds
the code to the makefiles which included them using make's conditional
processing.

This is being done because these dependency changes caused a regression.

For most situations, the loopback interface can depend on root instead
of localmount, so this patch makes that happen. It also adds comments to
the net.example files explaining when a user might want to change this
and giving an example.

Add support for optional fallback_routes_* variables in the network scripts.
This is similar to the fallback_route_* support in baselayout-1.
However, if you do not have fallback_routes set for an interface but you
do have routes set, that setting will be used, so you do not need this
variable unless you want the fallback routes to be different from the
primary routes.

This replaces the vlan setup code that previously used the old vconfig
binary with a new implementation using the iproute2 interface.
vconfig does not handle many of the newer setups. No automatic migration
path is provided, as altering the configuration is non-trivial.

Specifically document how to handle the case of explicitly starting a
bridge and then dynamically adding interfaces to it.
brctl_br0=''
bridge_add_eth0='br0'
This can be used for multi-homed connections and other advanced routing
in Linux. See the documentation links for more information about doing
this in linux.
The code was a originally pure addon into the conf.d/net files, written
in mid-2004 for doing multi-homing between two internet connections. I
have finally cleaned this up and integrated it. Thanks to Jonathan Kwan
for giving me the original impetus to develop this for Gentoo (it was
his dual internet connections...).
In the intervening years, it was a example of postup/postdown in the
net.example file, however that suffered from a few corner case issues.
If you were using the code from net.example, please see the updated
section 'Advanced Routing' on syntax, and drop your old function blocks.
Additionally, note that the rules added are now directly saved for
removal when the interface is taken down.
- Use sysfs to read bridge information from the system instead of
parsing the brctl outputs.
- Allow setting of all bridge configuration parameters using new sysfs
methods, modelled after bonding configuration. Also works for per-port
bridge interface parameters.
- Document pre-starting an empty bridge for dynamic add.
- Check for interface existence before adding to bridge.
- Should fix bug #293046, #309185.
