From: Artemy Kovalyov Date: Mon, 2 Jan 2017 09:37:42 +0000 (+0200) Subject: IB/mlx5: Refactor UMR post send format X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3161625589c1d7c54e949d462f4d0c327664881a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git IB/mlx5: Refactor UMR post send format * Update struct mlx5_wqe_umr_ctrl_seg. * Currenlty UMR send_flags aim only certain use cases: enabled/disable cached MR, modifying XLT for ODP. By making flags independent make UMR more flexible allowing arbitrary manipulations. * Since different UMR formats have different entry sizes UMR request should receive exact size of translation table update instead of number of entries. Rename field npages to xlt_size in struct mlx5_umr_wr and update relevant code accordingly. * Add support of length64 bit.
