Merge branch 'vxlan-fdb-flushing'
Amit Cohen says:
====================
Extend VXLAN driver to support FDB flushing
The merge commit 92716869375b ("Merge branch 'br-flush-filtering'") added
support for FDB flushing in bridge driver. Extend VXLAN driver to support
FDB flushing also. Add support for filtering by fields which are relevant
for VXLAN FDBs:
* Source VNI
* Nexthop ID
* 'router' flag
* Destination VNI
* Destination Port
* Destination IP
Without this set, flush for VXLAN device fails:
$ bridge fdb flush dev vx10
RTNETLINK answers: Operation not supported
With this set, such flush works with the relevant arguments, for example:
$ bridge fdb flush dev vx10 vni 5000 dst 193.2.2.1
< flush all vx10 entries with VNI 5000 and destination IP 193.2.2.1>
Some preparations are required, handle them before adding flushing support
in VXLAN driver. See more details in commit messages.
Patch set overview:
Patch #1 prepares flush policy to be used by VXLAN driver
Patches #2-#3 are preparations in VXLAN driver
Patch #4 adds an initial support for flushing in VXLAN driver
Patches #5-#9 add support for filtering by several attributes
Patch #10 adds a test for FDB flush with VXLAN
Patch #11 extends the test to check FDB flush with bridge
