From: Matan Barak <[email protected]> This commit revert "IB/core: Temporarily disable create_flow/destroy_flow uverbs" (commit d3bebb918d78755da505f56727cdde2d9c8adbe2). Since the uverbs extensions functionality was experimental for v3.12, this patch re-enables the support for them and flow-steering for v3.13.
