It maps a C struct directly onto on-the-wire API messages. +The client side C language binding is the same, while other language bindings have their own encoder/decoders. + +Multiple strings alone or combined with other variable length types turned out to be error prone to manually implement on the VPP side, +and not supported by VPP API (VAPI) very well at all. + +To avoid having to rewrite VAPI significantly, and to mitigate the risk +and error prone server side support of multiple variable length fields, +this patch extends strings to have a fixed size (on the wire) and +a variable flavour, as well as adding detection in the API compiler +to detect multiple variable length fields in a message (or type). + +Given that this change breaks the commitment to binary API compatibility, +normally present in point builds, ALL 19.08 build artifacts are being +deferred. + +This means the artifacts for the VPP 19.08.1 will be installed +in the release repository (packagecloud.io/fdio/release), then +ALL 19.08 build artifacts will be moved into the deferred repository +(packagecloud.io/fdio/deferred).
