+- buffer-manager: a phandle to a buffer manager node. Please refer to

+- bm,pool-long: ID of a pool, that will accept all packets of a size
+ higher than 'short' pool's threshold (if set) and up to MTU value.
+ Obligatory, when the port is supposed to use hardware
+ buffer management.
+- bm,pool-short: ID of a pool, that will be used for accepting
+ packets of a size lower than given threshold. If not set, the port
+ will use a single 'long' pool for all packets, as defined above.
