[PATCH v6 01/14] examples/l3fwd: fix queue ID restriction

[Sivaprasad Tummala]

Currently application supports queue IDs up to 255
and max queues of 256 irrespective of device support.
This limits the number of active lcores to 256.

The patch fixes these constraints by increasing
the queue IDs to support up to 65535.

Fixes: af75078fece3 ("first public release")
