This series adds userspace support for the Reorder Completion Queue (RCQ)
feature in the ionic RDMA driver.

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.

v2:
  - Dropped QP transport mode selection
v1:
  - https://lore.kernel.org/linux-rdma/20260430123931.3256130-1-abhijit.gangurde@amd.com/
