 This splits a payment into multiple pieces, that all have the same payment hash (so it is [vulnerable to a straddling attack](https://lists.linuxfoundation.org/pipermail/lightning-dev/2018-February/000993.html)). This means that the theoretical maximum payment amount can be higher. A receiver doesn't know how many parts a payment is split into. To avoid an attack where one part the MPP payment will never arrive and the HTLC consumes resources over too long, receivers must fail incoming HTLCs after a reasonable timeout, usually 60 seconds.
