Vivien Didelot says: ==================== net: dsa: remove .set_addr An Ethernet switch may support having a MAC address, which can be used as the switch's source address in transmitted full-duplex Pause frames. If a DSA switch supports the related .set_addr operation, the DSA core sets the master's MAC address on the switch. This won't make sense anymore in a multi-CPU ports system, because there won't be a unique master device assigned to a switch tree. Moreover this operation is confusing because it makes the user think that it could be used to program the switch with the MAC address of the CPU/management port such that MAC address learning can be disabled on said port, but in fact, that's not how it is currently used. To fix this, assign a random MAC address at setup time in the mv88e6060 and mv88e6xxx drivers before removing .set_addr completely from DSA. Changes in v3: - include fix for mv88e6060 switch MAC address setter. Changes in v2: - remove .set_addr implementation from drivers and use a random MAC. ==================== 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.
