From 7c49c9855a890ce32ea08f01366ecb221a027ad8 Mon Sep 17 00:00:00 2001 From: Allen Hubbe Date: Tue, 27 Dec 2016 19:12:28 -0500 Subject: [PATCH] NTB: ntb_test: add parameter for doorbell bitmask If the test attempts to clear doorbell bits that are invalid for the hardware, then the test will fail. Provide a parameter to specify the doorbell bits to clear. Set default doorbell bits that work for XEON.
