- Now that many changes hit the main repo, this series needs some rebasing (conflicts are not too difficult, but having this rebase run through a bit in the CI would be great). - From a compatibility pov, I am not fond of the rte_ip.h => rte_ip.h, rte_ip6.h split. Applications will need to be updated for something that was ambiguous so far: rte_ip.h defined all symbols, regardless of IPv4 and IPv6. What do you think of keeping a rte_ip.h compat header that just includes new rte_ip4.h and rte_ip6.h headers? - With current patch, since only rte_ip.h is parsed in doxygen, we lost documentation for IPv6. Regardless of keeping a compat header, doc/api/doxy-api-index.md needs some update. - bonus 1: It would be worth cleaning unneeded includes in rte_ip*.h. But changing this is risky if we want to take this series in rc1. Please don't do this in next revision, this will wait after merging this series. For example, running iwyu returns: lib/net/rte_ip.h should remove these lines: - #include <arpa/inet.h> // lines 26-26 - #include <netinet/ip6.h> // lines 28-28 - #include <rte_mbuf.h> // lines 33-33 - #include <sys/socket.h> // lines 23-23 - #include <sys/types.h> // lines 24-24 lib/net/rte_ip6.h should remove these lines: - #include <arpa/inet.h> // lines 26-26 - #include <netinet/ip6.h> // lines 27-27 - #include <rte_mbuf.h> // lines 31-31 - #include <sys/socket.h> // lines 23-23 - bonus 2: Would it be possible to provide a cocci script or some shellscript for an application to convert to the updated APIs (especially the impact on rte_flow and other structures)? We did something similar for the prefixing of dpdk structures with RTE_. Idem, not necessary for rc1. -- David Marchand
