Nikolay Aleksandrov says: ==================== net: bridge: MTU handling changes As previously discussed the recent changes break some setups and could lead to packet drops. Thus the first patch reverts the behaviour for the bridge to follow the minimum MTU but also keeps the ability to set the MTU to the maximum (out of all ports) if vlan filtering is enabled. Patch 02 is the bigger change in behaviour - we've always had trouble when configuring bridges and their MTU which is auto tuning on port events (add/del/changemtu), which means config software needs to chase it and fix it after each such event, after patch 02 we allow the user to configure any MTU (ETH_MIN/MAX limited) but once that is done the bridge stops auto tuning and relies on the user to keep the MTU correct. This should be compatible with cases that don't touch the MTU (or set it to the same value), while allowing to configure the MTU and not worry about it changing afterwards. The patches are intentionally split like this, so that if they get accepted and there are any complaints patch 02 can be reverted. ==================== Signed-off-by: David S.

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.
