From a93b632c4531ff50c43d658447a45cbc11f488fd Mon Sep 17 00:00:00 2001 From: Maor Gottlieb Date: Sun, 1 Jul 2018 15:50:17 +0300 Subject: [PATCH] IB/mlx5: Fix GRE flow specification Currently the driver sets the mask of the gre_protocol to 0xffff without consideration in the user request. Fix it by copy the mask from the verbs spec.
