Hi, bnxt_re-abi.h in linux kernel and rdma-core uses abi version 1. We dont bump up the version in upstream and backward compatibility is maintained using the comp_mask field of the interface structures. If you are using the latest drivers maintained in the Broadcom site (which uses ABI version 6), you need to use the libbnxt_re hosted in the Broacom site itself. We maintain compatibility between the Out of tree driver and Out of tree library.
