From 2572cf57d75a7f91835d9a38771e9e76d575d122 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Mon, 5 Feb 2018 16:24:52 +0200 Subject: [PATCH] mlx5: fix mlx5_get_vector_affinity to start from completion vector 0 The consumers of this routine expects the affinity map of of vector index relative to the first completion vector. The upper layers are not aware of internal/private completion vectors that mlx5 allocates for its own usage. Hence, return the affinity map of vector index relative to the first completion vector.
