The current bridge kernel doc is too old. It only pointed to the linuxfoundation wiki page which lacks of the new features. Here let's start the new bridge document and put all the bridge info so new developers and users could catch up the last bridge status soon. In this patch, Convert the doc to rst format. Add bridge brief introduction, FAQ and contact info.

Introduction
|
|
============
|
|
|
|
The IEEE 802.1Q-2022 (Bridges and Bridged Networks) standard defines the
|
|
operation of bridges in computer networks. A bridge, in the context of this
|
|
standard, is a device that connects two or more network segments and operates
|
|
at the data link layer (Layer 2) of the OSI (Open Systems Interconnection)
|
|
model. The purpose of a bridge is to filter and forward frames between
|
|
different segments based on the destination MAC (Media Access Control) address.

FAQ
|
|
===
|
|
|
|
What does a bridge do?
|
|
----------------------
|
|
|
|
A bridge transparently forwards traffic between multiple network interfaces.
|
|
In plain English this means that a bridge connects two or more physical
|
|
Ethernet networks, to form one larger (logical) Ethernet network.
|
|
|
|
Is it L3 protocol independent?
|
|
------------------------------
|
|
|
|
Yes. The bridge sees all frames, but it *uses* only L2 headers/information.
|
|
As such, the bridging functionality is protocol independent, and there should
|
|
be no trouble forwarding IPX, NetBEUI, IP, IPv6, etc.

|
|
are discussed on the linux-netdev mailing list netdev@vger.kernel.org and
