Say Y to support traffic policing (bandwidth limits). Needed for
ingress and egress rate limiting.
To compile this code as a module, choose M here: the
module will be called pedit.
config NET_ACT_SIMP
tristate "Simple action"
tristate "Simple Example (Debug)"
depends on NET_CLS_ACT
---help---
You must have new iproute2 to use this feature.
This adds a very simple action for demonstration purposes
The idea is to give action authors a basic example to look at.
All this action will do is print on the console the configured
policy string followed by _ then packet count.
Say Y here to add a simple action for demonstration purposes.
It is meant as an example and for debugging purposes. It will
print a configured policy string followed by the packet count
to the console for every packet that passes by.
If unsure, say N.
To compile this code as a module, choose M here: the
module will be called simple.
config NET_CLS_POLICE
bool "Traffic Policing (obsolete)"
depends on NET_SCHED && NET_CLS_ACT!=y
select NET_ESTIMATOR
---help---
Say Y here if you want to do traffic policing, i.e. strict
bandwidth limiting. This option is obsoleted by the traffic
policer implemented as action, it stays here for compatibility
reasons.
config NET_CLS_IND
bool "Incoming device classification"
depends on NET_SCHED && (NET_CLS_U32 || NET_CLS_FW)
---help---
Say Y here to extend the u32 and fw classifier to support
classification based on the incoming device. This option is
likely to disappear in favour of the metadata ematch.
config NET_ESTIMATOR
bool "Rate estimator"
depends on NET_SCHED
---help---
Say Y here to allow using rate estimators to estimate the current
rate-of-flow for network devices, queues, etc. This module is
automaticaly selected if needed but can be selected manually for
statstical purposes.
