Two related changes for the HiSilicon hi3516cv6xx (CV608/CV610/CV613) family:

1. Kernel: enable CONFIG_TUN=m in hi3516cv6xx.generic.config. Builds the TUN/TAP driver as a loadable module, bringing cv6xx to parity with all other HiSilicon board configs (which already ship CONFIG_TUN=m). Needed for userspace VPN / ZeroTier / WireGuard-go / tunnel use on these boards.

2. Userspace: enable BR2_PACKAGE_VTUND_OPENIPC=y on the cv6xx lite defconfig. Matches the ultimate variant (which already ships it) and other board lite defconfigs. Provides the vtun/tunnel helper to go with the kernel TUN module above.

Enable TUN/TAP module for HiSilicon hi3516cv6xx boards

⚙️ Configuration changes ✨ Enhancement 🕐 Less than 5 minutes

AI Description

• Enable TUN/TAP as a loadable kernel module for the hi3516cv6xx family.
• Support userspace tunnel applications and match other HiSilicon board configurations.

High-Level Assessment

Keep the module setting in the shared hi3516cv6xx kernel configuration: both lite and ultimate builds reference it, and CONFIG_TUN=m matches the other HiSilicon boards. A built-in driver would use kernel image space unnecessarily.

• Changes CONFIG_TUN from disabled to a loadable module in the shared hi3516cv6xx kernel configuration. This makes TUN/TAP available to userspace tunnel applications when the module is installed and loaded.

1. TUN module ships without board evidence 📘 Rule violation ◔ Observability

Description

CONFIG_TUN=m replaces the disabled CONFIG_TUN line in hi3516cv6xx.generic.config, so every
image built from this family's kernel config now carries a loadable TUN/TAP module that did not
exist before. The description gives only a parity rationale (other HiSilicon configs already set it)
and names no symptom, no affected board, and no before/after output from a real camera, which the
hardware-evidence gate requires for any change that alters what the firmware does on a device.

Code

br-ext-chip-hisilicon/board/hi3516cv6xx/hi3516cv6xx.generic.config[1122]

+CONFIG_TUN=m

Evidence

The only hunk changes line 1122 from # CONFIG_TUN is not set to CONFIG_TUN=m. The PR description
states the purpose ('Needed for userspace VPN / ZeroTier / WireGuard-go / tunnel use') and parity
with other boards, but contains no verification section, no checkboxes, and no log, dmesg, or
module-load output from a camera. The change itself adds a kernel module to the shipped image, so it
is an image-altering change under checklist item 3.

Rule 3: Hardware evidence is present and honest

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The PR flips `CONFIG_TUN` from disabled to `CONFIG_TUN=m` for the hi3516cv6xx family (br-ext-chip-hisilicon/board/hi3516cv6xx/hi3516cv6xx.generic.config, line 1122). This adds a TUN/TAP module to every image built from that config, but the description only gives a parity rationale and no evidence from hardware.
## Fix Focus Areas
- br-ext-chip-hisilicon/board/hi3516cv6xx/hi3516cv6xx.generic.config[1122-1122]
## Recommended Fix
Update the PR description to name the symptom or use case the change fixes and the affected board(s). Attach real output from a camera built with this config: `lsmod` or `modprobe tun` result, `ls -l /dev/net/tun`, and a dmesg excerpt. If hardware testing was not done, say so plainly and give the evidence the change class allows, such as a build artifact check confirming `tun.ko` is present in the image.
