Subject: [PATCH RFC 05/12] vdpa_sim: remove the limit of IOTLB entries
Date:   Fri, 13 Nov 2020 14:47:05 +0100

The simulated devices can support multiple queues, so this limit
should be defined according to the number of queues supported by
the device.

Since we are in a simulator, let's simply remove that limit.
