checksum-checks:
description: "Opt for the checksum verification mode suitable for the interface. During capture, it's possible that some packets may exhibit invalid checksums due to the network card handling the checksum computation. You have several options: 'kernel': Relies on indications sent by the kernel for each packet (default). 'yes': Enforces checksum validation. 'no': Disables checksum validation. 'auto': Suricata employs a statistical approach to detect checksum offloading."
