- Update to 1.2.2
- Support including UCX API headers from C++ code
- UD transport to handle unicast flood on RoCE fabric
- Compilation fixes for gcc 7.1.1, clang 3.6, clang 5
- When UD transport is used with RoCE, packets intended for other peers may
arrive on different adapters (as a result of unicast flooding).
- This change adds packet filtering based on destination GIDs. Now the packet
is silently dropped, if its destination GID does not match the local GID.
- Added a new device ID for InfiniBand HCA
