This is primarily for users with set_name_type settings from previous
sysadmins can easily see what changes to make.

Implement a consistent interface for changing ethtool parameters, as
suggested in bug 195479. All variable names are based on the long option
to ethtool to set each group of parameters. Multiple entries seperated
by newlines are permitted for variable values.

X-Gentoo-Bug: 195479
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.

X-Gentoo-Bug: 346365
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.
