Subject: [PATCH v6 1/9] hw: Add check for queue number
Date: Tue, 27 Apr 2021 11:39:43 +0800 [thread overview]
Message-ID: <20210427033951.29805-2-lulu@redhat.com> (raw)
In-Reply-To: <20210427033951.29805-1-lulu@redhat.com>
In order to support configure interrupt. we will use queue number -1
as configure interrupt
since all these device are not support the configure interrupt
So we will add an check here, if the idx is -1, the function
will return;
