Sławek Kapłoński 45410d76be Add support for QoS for LinuxBridge agent
There is a new QoS extension driver for the linuxbridge agent
being added. This driver provides support for QoS configuring
on the linuxbridge agent.
This patch introduces two new config options for Linuxbridge agent:
kernel_hz - HZ value of host kernel,
tbf_latency - value of latency in tbf qdisc to calculate size of queue.

The LinuxBridge agent now supports QoS bandwidth limiting.
features:
- The LinuxBridge agent can now configure basic bandwidth limiting
QoS rules set for ports and networks.
It introduces two new config options for LinuxBridge agent.
First is 'kernel_hz' option which is value of host kernel HZ
setting. It is necessary for proper calculation of minimum burst
value in tbf qdisc setting.
Second is 'tbf_latency' which is value of latency to be configured
in tc-tbf setting. Details about this option can be found in
`tc-tbf manual <http://linux.die.net/man/8/tc-tbf>`_.
