Increase Packet Queue Size

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
