+// Package packet contains packet parsing and marshaling utilities.
+//
+// Parsed provides allocation-free minimal packet header decoding, for
+// use in packet filtering. The other types in the package are for
+// constructing and marshaling packets into []bytes.
+//
+// To support allocation-free parsing, this package defines IPv4 and
+// IPv6 address types. You should prefer to use netaddr's types,
+// except where you absolutely need allocation-free IP handling
+// (i.e. in the tunnel datapath) and are willing to implement all
+// codepaths and data structures twice, once per IP family.
