// TODO: At the moment, the collator protocol uses notifications protocols to download
// collations. Because of DoS-protection measures, notifications protocols have a very limited
// bandwidth capacity, resulting in the collation download taking a long time.
// The lines of code below considerably relaxes this DoS protection in order to circumvent
// this problem. This configuraiton change should preferably not reach any live network, and
// should be removed once the collation protocol is finished.
// Tracking issue: https://github.com/paritytech/polkadot/issues/2283
