From bb3877dde3d1403806092d121d64616c332a950c Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Tue, 8 Nov 2022 21:43:35 +0100 Subject: vhost-user: compare mode MODE_PASTA and not MODE_PASST As we are going to introduce the MODE_VU that will act like the mode MODE_PASST, compare to MODE_PASTA rather than to add a comparison to MODE_VU when we check for MODE_PASST.
