[Bridge] [PATCH net-next 1/2] bridge: Add a limit on FDB entries
A malicious actor behind one bridge port may spam the kernel with packets
with a random source MAC address, each of which will create an FDB entry,
each of which is a dynamic allocation in the kernel.
There are roughly 2^48 different MAC addresses, further limited by the
rhashtable they are stored in to 2^31. Each entry is of the type struct
net_bridge_fdb_entry, which is currently 128 bytes big.

That name is too long.
Also, all the rest of bridge code does not use sysctl's. Why is this
special and why should the property be global and not per bridge?
