### uint32\_t max\_pkt\_cache

PDCP entities may hold packets for purposes of in-order delivery (in case of receiving PDCP entity) and re-transmission (in case of transmitting PDCP entity).

The field 'max\_pkt\_cache' would be used to indicate the maximum number of packets that may be cached in an entity at any point of time. When application provides buffers to receive packets from PDCP entity, the size of the buffer should be such that it can hold additionally 'max\_pkt\_cache' number of packets.
