From 64f817ba98095156149ba5991592d5d039f6da74 Mon Sep 17 00:00:00 2001 From: Ralph Campbell Date: Fri, 22 Sep 2006 15:22:24 -0700 Subject: IB/uverbs: Allow resize CQ operation to return driver-specific data Add a ib_uverbs_resize_cq_resp.driver_data field so that low-level drivers can return data from a resize CQ operation to userspace. Have ib_uverbs_resize_cq() only copy the cqe field, to avoid having to bump the userspace ABI.
