From a48bc513159d4767f9988f0d857b2b0c38a4d614 Mon Sep 17 00:00:00 2001 From: Huy Nguyen Date: Tue, 11 Sep 2018 14:58:22 -0500 Subject: [PATCH] net/mlx5: Take only bit 24-26 of wqe.pftype_wq for page fault type The HW spec defines only bits 24-26 of pftype_wq as the page fault type, use the required mask to ensure that.
