How can i use 4 ports for ethernet?

[kimsj]

Hi, i am doing a project that making AVB switch using Daisy chain.

But in the ethernet MAC 2 layer reference, they only implemented using 2ports for ethernet.

how can i modify the code to make 4 port to use ethernet?

and also i am struggling about constructing the avb packet scheduling..

is there any references or methods to do this?

Please reply.

thanks
