iproute2/ip/iplink_bridge.c
Johannes Nixdorf 48cb432048 iplink: bridge: Add support for bridge FDB learning limits 
Support setting the FDB limit through ip link. The arguments is:
 - fdb_max_learned: A 32-bit unsigned integer specifying the maximum
                    number of learned FDB entries, with 0 disabling
                    the limit.

Also support reading back the current number of learned FDB entries in
the bridge by this count. The returned value's name is:
 - fdb_n_learned: A 32-bit unsigned integer specifying the current number
                  of learned FDB entries.

Example:

 # ip -d -j -p link show br0
[ {
...
        "linkinfo": {
            "info_kind": "bridge",
            "info_data": {
...
                "fdb_n_learned": 2,
                "fdb_max_learned": 0,
...
            }
        },
...
    } ]
 # ip link set br0 type bridge fdb_max_learned 1024
 # ip -d -j -p link show br0
[ {
...
        "linkinfo": {
            "info_kind": "bridge",
            "info_data": {
...
                "fdb_n_learned": 2,
                "fdb_max_learned": 1024,
...
            }
        },
...
    } ]
