rdma-core-headers

Public API headers for libibverbs and librdmacm extracted from rdma-core.

These headers are used for dynamically loading the RDMA libraries at runtime, allowing binaries to be built without requiring rdma-core development packages installed.

Updating

1. Clone rdma-core:

   git clone --depth=1 https://github.com/linux-rdma/rdma-core.git /tmp/rdma-core

2. Copy the public headers from libibverbs:

   cp /tmp/rdma-core/libibverbs/{arch,opcode,sa-kern-abi,sa,verbs,verbs_api,tm_types}.h include/infiniband/

3. Copy the public headers from librdmacm:

   cp /tmp/rdma-core/librdmacm/{rdma_cma,rdma_cma_abi,rdma_verbs,rsocket}.h include/rdma/
   cp /tmp/rdma-core/librdmacm/{acm,ib}.h include/infiniband/

4. Copy the kernel ABI headers:

   cp /tmp/rdma-core/kernel-headers/rdma/ib_user_ioctl_verbs.h include/infiniband/
   cp /tmp/rdma-core/kernel-headers/rdma/{ib_user_sa,ib_user_verbs}.h include/rdma/

5. Update this README with the new commit hash and date.
