From 7756e2b5d68c36e170a111dceea22f7365f83256 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Tue, 28 Aug 2018 17:13:59 -0700 Subject: ntb: intel: fix return value for ndev_vec_mask() ndev_vec_mask() should be returning u64 mask value instead of int. Otherwise the mask value returned can be incorrect for larger vectors.
