This is an intermidiate driver that allows sharing of
resources.
To compile this driver as a module, choose M here: the module
will be called ifb. If you want to use more than one ifb
device at a time, you need to compile this driver as a module.
Instead of 'ifb', the devices will then be called 'ifb0',
'ifb1' etc.

/* drivers/net/ifb.c:
The purpose of this driver is to provide a device that allows
for sharing of resources:
1) qdiscs/policies that are per device as opposed to system wide.
ifb allows for a device which can be redirected to thus providing
an impression of sharing.
2) Allows for queueing incoming traffic for shaping instead of
dropping.
The original concept is based on what is known as the IMQ
driver initially written by Martin Devera, later rewritten
by Patrick McHardy and then maintained by Andre Correa.
You need the tc action mirror or redirect to feed this device
packets.
