My take from "announced ABI breakage" is the deprecation notice get three acks and merged into release, so it seems there is no deprecation notice and according process first deprecation notice should go in this release.

To be honest I lost track of Xueming's patches, because of split/merge of patchset, multiple set with multiple versions out. Is it possible to document the dependency graph including your set? > > [1] "doc: announce API changes for flow rules" > http://dpdk.org/ml/archives/dev/2018-February/090988.html > [2] "MLX5 tunnel Rx offloading" > http://dpdk.org/ml/archives/dev/2018-February/091461.html > [3] "doc: annouce ABI change for RSS configuraiton structure" > http://dpdk.org/ml/archives/dev/2018-February/090127.html > [4] "tunnel endpoint hw acceleration enablement" > http://dpdk.org/ml/archives/dev/2017-December/084676.html > [5] "Switch device offload with DPDK" > http://dpdk.org/ml/archives/dev/2018-March/092513.html > >>> Signed-off-by: Adrien Mazarguil >>> Acked-by: Andrew Rybchenko >> >> <...> >> >
