Patch 1 extends the net/ionic firmware identity structure to expose the rcq_sign_bit field from the RDMA LIF identity. Patch 2 plumbs the RCQ sign bit through the RDMA driver's LIF configuration, exposes it to userspace via the ucontext response, and allows userspace to specify ionic specific QP flags during QP creation. This enables rdma-core to discover RCQ capability at context allocation time and configure QPs with RCQ support.
