Yes, the API and ABI changes are described in the release notes: http://dpdk.org/browse/dpdk/tree/doc/guides/rel_notes/release_16_04.rst#n471 And the next deprecations are announced in another section: http://dpdk.org/browse/dpdk/tree/doc/guides/rel_notes/deprecation.rst PS: please answer inline ----------------- > From: Thomas Monjalon [mailto:thomas.monjalon@6wind.com] > 2016-04-06 08:34, Weglicki, MichalX: > > Hello, > > > > I have a question about this patch. > > > > As far as I see changing ETH_LINK_SPEED_ to ETH_SPEED_NUM_ is rather cosmetic change, am I right? > > No. > ETH_LINK_SPEED was used for configuration and reported speed. > Now the configuration is done with a bitmap filled with new ETH_LINK_SPEED > and the old numerical values are kept for other usages as ETH_SPEED_NUM. > > > Disadvantage of that is that it breaks compatibility with OVS (compilation) and thus it also breaks backward compatibility between OVS & DPDK.
