Ido Schimmel says: ==================== Add MDB bulk deletion support This patchset adds MDB bulk deletion support, allowing user space to request the deletion of matching entries instead of dumping the entire MDB and issuing a separate deletion request for each matching entry. Support is added in both the bridge and VXLAN drivers in a similar fashion to the existing FDB bulk deletion support. The parameters according to which bulk deletion can be performed are similar to the FDB ones, namely: Destination port, VLAN ID, state (e.g., "permanent"), routing protocol, source / destination VNI, destination IP and UDP port. Flushing based on flags (e.g., "offload", "fast_leave", "added_by_star_ex", "blocked") is not currently supported, but can be added in the future, if a use case arises. Patch #1 adds a new uAPI attribute to allow specifying the state mask according to which bulk deletion will be performed, if any. Patch #2 adds a new policy according to which bulk deletion requests (with 'NLM_F_BULK' flag set) will be parsed. Patches #3-#4 add a new NDO for MDB bulk deletion and invoke it from the rtnetlink code when a bulk deletion request is made. Patches #5-#6 implement the MDB bulk deletion NDO in the bridge and VXLAN drivers, respectively. Patch #7 allows user space to issue MDB bulk deletion requests by no longer rejecting the 'NLM_F_BULK' flag when it is set in 'RTM_DELMDB' requests. Patches #8-#9 add selftests for both drivers, for both good and bad flows. iproute2 changes can be found here [1]. https://github.com/idosch/iproute2/tree/submit/mdb_flush_v1 ==================== Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
