Currently, the info structure contains the maximum number
of sessions that a device can manage.
This field was useful when the session mempool was created inside
each device, but now it is created at the application level.
Most PMDs do not have a limitation on the sessions managed,
but a few do, therefore this field must remain in the structure.
However, a new value, 0, can be used to indicate that
a device does not have an actual maximum of sessions.
