CONFIG_TUN_VNET_CROSS_LE: Support for cross-endian vnet headers on little-endian kernels

General informations

The Linux kernel configuration item CONFIG_TUN_VNET_CROSS_LE:

• prompt: Support for cross-endian vnet headers on little-endian kernels
• type: bool
• depends on: (none)
• defined in drivers/net/Kconfig
• found in Linux kernels: 4.2–4.20, 5.0–5.19, 6.0–6.12

Help text

This option allows TUN/TAP and MACVTAP device drivers in a little-endian kernel to parse vnet headers that come from a big-endian legacy virtio device.

Userspace programs can control the feature using the TUNSETVNETBE and TUNGETVNETBE ioctls.

Unless you have a little-endian system hosting a big-endian virtual machine with a legacy virtio NIC, you should say N.
