[Bridge] [PATCH net-next v2 0/3, iproute2-next 0/1] bridge: Add a limit on learned FDB entries
Introduce a limit on the amount of learned FDB entries on a bridge,
configured by netlink with a build time default on bridge creation in
the kernel config.
For backwards compatibility the kernel config default is disabling the
limit (0).
Without any limit a malicious actor may OOM a kernel by spamming packets
with changing MAC addresses on their bridge port, so allow the bridge
creator to limit

[Bridge] [PATCH net-next V5 00/14] Add basic VLAN support to bridges
This series of patches provides an ability to add VLANs to the bridge
ports. This is similar to what can be found in most switches. The bridge
port may have any number of VLANs added to it including vlan 0 priority tagged
traffic. When vlans are added to the port, only traffic tagged with particular
vlan will forwarded over this port. Additionally, vlan ids are added to FDB
entries and become

[Bridge] [PATCH v10 net-next 00/12] VLAN filtering/VLAN aware bridge
Changes since v9:
* series re-ordering so make functionality more distinct. Basic vlan
filtering is patches 1-4. Support for PVID/untagged vlans is patches
5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is
still additional egress policy.
* Slight simplification to code that extracts the VID from skb. Since we
now depend on the vlan module, at the time of input skb_tci is
