@page lidar_usecase3 Increase Packet Queue Size 

@note SW Release Applicability: This tutorial is applicable to modules in both **NVIDIA DriveWorks** and **NVIDIA DRIVE Software** releases.

Velodyne HDL32E, Velodyne VLP32C and Velodyne HDL64E packets are stored in a queue in kernel space 
and the size cannot be controlled directly by the application.

However, in case of packet drops it is possible to increase the size with the following commands:

    sudo sysctl -w net.core.rmem_max=16777216
    sudo sysctl -w net.core.rmem_default=16777216
