From 32269441240064c7475241ae28fee787fcdf55b9 Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Mon, 23 Jul 2018 15:25:09 +0300 Subject: IB/mlx5: Introduce driver create and destroy flow methods Introduce driver create and destroy flow methods on the uverbs flow object. This allows the driver to get its specific device attributes to match the underlay specification while still using the generic ib_flow object for cleanup and code sharing. The IB object's attributes are set via the ib_set_flow() helper function. The specific implementation for the given specification is added in downstream patches.
