a6db2374fe Bug #427152: Port of VLAN code to sysfs/iproue2 from vconfig lost the ability to create different vlans with the same ID but different interfaces on a single system. Implement it now.

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).

76d3fceb58 doc/net.example: Update bonding example
The newer bonding code using sysfs does not clearly show the most common
bond parameter: mode

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

44e4c21f05 net: fix documentation for interface dependencies
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.

380752f4e0 net: allow parameters to a single address config
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.

9a01f68515 net: Add up_before_preup variable for CAN devices
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

8e925368b7 bring up the loopback interface earlier
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.

I would like to thank Robin Johnson for the original patch and suggested
examples.

15660dbbfc add fallback_routes support to network scripts
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.

683a21b0a0 net/vlan: update to use modern iproute2 interface
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.

e07f0ef417 Merge support for Routing Policy Database (RPDB)
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.

dbb5af2023 Revamp of bridging code.
- 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.
