In linux its possible to assign an ip address to a vlan-aware bridge
For some use cases is it useful to restrict users from configuring ips on
bridges VA. This patch will let admins and distributions decide if it is
necessary to warn the user in such case.
The patch introduces a new configuration variable in:
/etc/network/ifudpown2/ifupdown2.conf
vlan_aware_bridge_address_support: yes|no|on|off|0|1 (default to yes)
[8:30:41] root:~ # cat /etc/network/ifupdown2/ifupdown2.conf | grep "vlan_aware_bridge_address_support"
[8:30:43] root:~ # ifquery bridge
auto bridge
iface bridge
bridge-ports swp1
bridge-vlan-aware yes
address 10.10.10.10
[8:30:46] root:~ # ifup bridge --syntax-check
[8:30:52] root:~ # echo $?
0
[8:30:54] root:~ # echo "vlan_aware_bridge_address_support=no" >> /etc/network/ifupdown2/ifupdown2.conf
[8:31:11] root:~ # ifup bridge --syntax-check
warning: bridge: ignoring ip address. Assigning an IP address is not allowed on bridge vlan aware interfaces

This is a major update coming all at once from master-next branch
master-next branch was started with --orphan option which is basically a new
branch without history.
The major changes are:
- repackaging
- cleanup the directory tree
- rewritte setup.py to allow install from deb file or pypi (pip install)
- add a Makefile to make things (like building a deb) easier
- review all debian files
