From 525ae115222f0b0b6de7f9665976f640d18c200a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Eugenio=20P=C3=A9rez?= Date: Tue, 17 Jan 2023 11:53:08 +0100 Subject: vdpa: fix VHOST_BACKEND_F_IOTLB_ASID flag check MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit VHOST_BACKEND_F_IOTLB_ASID is the feature bit, not the bitmask. Since the device under test also provided VHOST_BACKEND_F_IOTLB_MSG_V2 and VHOST_BACKEND_F_IOTLB_BATCH, this went unnoticed.
