From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Changelog: v0->v1: https://lore.kernel.org/linux-rdma/20191027070621.11711-1-leon@xxxxxxxxxx * Used Jason's macros as a basis for all get/set operation for wire protocol. * Fixed wrong offsets * Grouped all CM related patches in one patchset bomb ---------------------------------------------------------------------- Hi, This series continues already started task to clean up CM related code. Over the years, the IB/core gained a number of anti-patterns which led to mistakes. First and most distracting is spread of hardware specification types (e.g. __beXX) to the core logic. Second, endless copy/paste to access IBTA binary blobs, which made any IBTA extensions not an easy task. In this series, we add Enhance Connection Establishment bits which were added recently to IBTA and will continue to convert rest of the CM code to propose macros by eliminating __beXX variables from core code. All IBTA CM declarations are places into new header file: include/rdma/ibta_vol1_c12.h and the idea that every spec chapter will have separate header file, so we will see immediately the relations between declarations and values. Thanks BTW, 1. The whole area near private_data looks sketchy to me and needs separate cleanup. 2. I know that it is more than 15 patches, but they are small and self-contained.
