Running Zeek with Napatech SmartNICs

Use the load distribution feature of Napatech SmartNICs to improve performance of Zeek.

This describes a configuration example to use the load distribution feature of Napatech SmartNICs which improves performance of Zeek.

Configure SmartNICs as described in SmartNIC Configuration.
Edit the /opt/napatech3/etc/node.cfg file. Add Napatech interfaces between nt3g0 and nt3g15. Each of your worker nodes must be pinned to a target CPU core using the pin_cpus parameter. This is what worker nodes should look like using Napatech interfaces and CPU pinning.
```
...
#
[worker-1]
type=worker
host=localhost
interface=nt3g0
pin_cpus=0
#
[worker-2]
type=worker
host=localhost
interface=nt3g1
pin_cpus=1
...
#
[worker-15]
type=worker
host=localhost
interface=nt3g14
pin_cpus=14
#
[worker-16]
type=worker
host=localhost
interface=nt3g15
pin_cpus=15
```
Run deploy in the ZeekControl shell, after the Zeek configuration file is modified.
```
[ZeekControl] > deploy
```
Start the monitoring and profiling tools for performance monitoring. See SmartNIC Performance Monitoring.
