Plans to support traffic limit for a MAC address #105

Hi,

Great project and I see a lot of momentum on it right now. Is there any plans to support traffic control using device MAC address ?

Hi @NetForces,

Could you tell me more the details about "traffic limit for a MAC address"? I am not sure what exactly means that.

Are you imagine the followings or any other ideas?

L2 level traffic control
- this would probably impossible because of tc command not supported the feature
source/destination specifier options like --dst-macaddr/--src-macaddr
- get a target IP address to incur traffic control from a mac address
- this could be possible, but I am not sure the use cases

Yup options like --dst-macaddr/--src-macaddr

In a dynamic system where devices on the network get their IP from a DHCP server, the device IP may change over time. While a process to catch these and change the tc rules dynamically is possible it's a real pain. Using the mac address for traffic control means that you set it once for a physical device and do not have to touch it anymore, independant of it's IP address.

Thank you for your explanation.

I understand the use case. I will consider the feature for the future release.
