// Top level for bridge example
//
// 4-port bridge has 4 GMII interfaces, each one of which has its own RX clock
// Port macros contain all packet buffering, and ring interface to communicate
// with other port macros.
// FIB block receives requests from all ports and sends results back to the
// same port containing forwarding information.
