A code-quality pass over the periphery. The packet crate frames a message with `begin_message` and `finish_message`, which the exporter's hand-written UPDATE header can use instead of a bare type code, and keeps the NLRI reader and writer together as a pair; the rule that the body's prefixes are IPv4 unicast lives once; a session with two-octet AS numbers no longer reserves the attributes' wire copy it never keeps. The TCP diagnostics read netlink with the netlink module's own attribute walk and helpers instead of copies of them. The kernel follower learns what the kernel has in one named step used at start and on relearning, keeps its batch buffers between wakes, and builds its task in a constructor. The mesh benchmark, which had grown six phases in one main, is a `Mesh` with named phases and a `Receiver`, with one report of the sessions for both deadlines; the collector capabilities, the KEEPALIVE bytes, the draining of a session and the printing of a table row are helpers shared by the benches, the examples and the integration tests. The MRT reader uses the packet crate's attribute splitter. Testing: a message framed by hand is the one `to_wire` writes; a short tcp_info from an old kernel leaves the later fields zero; the synthetic table is the same every run and every announcement decodes to itself. The packing example gives the same figures on the RIS dump before and after. The crates' tests, the integration tests, the kernel tests and every lab phase pass.

BGP Packet
This crate implements parsers and serialisers for the Border Gateway Protocol wire format.
It is used by the daemon in bin/bgp, and tested with property tests
(tests/properties.rs) and fuzz targets (fuzz/).
