Robert Klotzner fe30849eec Fix #1778: Double mdns recv_buffer to 4096 bytes (#1779)
Also add warn if parsing of a packet fails, so problems with for example packet
sizes can more easily be detected.

Reasoning:

The previous 2048 bytes is already larger than the recommend size by
[rfc6762](https://tools.ietf.org/html/rfc6762#page-46), which recommends
a packet size that fits within the interface MTU.

Nevertheless the rfc also states, that if more data needs to be
transmitted one should rely on IP fragments, which would only pose
problems when interfacing with devices not understanding IP fragments.
The standard also imposes a strict upper limit of 9000 bytes.

Therefore raising `recv_buffer` to 4096 seems sensible, given that we
already exceed the recommend size and given that we are not restricting
the size when sending in any way. Meaning the implementation already
sends packets larger than recommended, just can't handle them on
reception.

Central repository for work on libp2p

dependency status

This repository is the central place for Rust development of the libp2p spec.

Warning: While we are trying our best to be compatible with other libp2p implementations, we cannot guarantee that this is the case considering the lack of a precise libp2p specifications.
