As Roopa noted today the biggest source of problems when configuring bridge and ports is that the bridge MTU keeps changing automatically on port events (add/del/changemtu). That leads to inconsistent behaviour and network config software needs to chase the MTU and fix it on each such event. Let's improve on that situation and allow for the user to set any MTU within ETH_MIN/MAX limits, but once manually configured it is the user's responsibility to keep it correct afterwards. In case the MTU isn't manually set - the behaviour reverts to the previous and the bridge follows the minimum MTU.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
