и для TCP (в частности, для Path MTU Discovery).
RFC 2923:
PMTUD, as documented in [RFC1191], fails when the appropriate ICMP
messages are not received by the originating host. The upper-layer
protocol continues to try to send large packets and, without the ICMP
messages, never discovers that it needs to reduce the size of those
packets. Its packets are disappearing into a PMTUD black hole.
