The existing taildrop was based on queue data size.
This patch replaces it with frame count bases using
CGR methods of DPAA2 device.
The number of CGRs are limited. So,
- use per queue CGR based tail drop for as many as CGR
available.
- Remaining queues shall use the legacy byte based tail drop
Number of CGRs can be controlled by dpl file during dpni_create.
