Change MAX_QUEUES from 512 to 128 to reduce the number of hugepages required by the vhost-switch program. To change MAX_QUEUES add '-D MAX_QUEUES=512' to the EXTRA_CFLAGS variable, before building the application. Changes in v3: Added #ifndef MAX_QUEUES line before #define MAX_QUEUES 128 Changes in v2: remove comment added before #define MAX_QUEUES in v1 patch.
