en: MT7601U driver performance note; VStarcam Hi3518EV200+GC2023 device page

[phedoreanu]

Two additions from converting a VStarcam Hi3518EV200 pan/tilt camera:

adding-wifi-driver.md — a note under MediaTek that the mainline mt7601u and the vendor-lineage mt7601sta (what BR2_PACKAGE_MT7601U_OPENIPC builds) are not equivalent. Measured on the same camera, dongle, AP and channel: 0.4–1.0 Mbps transmit on mainline (with mt7601u_mcu_wait_resp retrying in dmesg) vs 15–17 Mbps on the STA driver — the difference between an RTSP stream that lags by seconds and one that keeps its send queue empty. Also warns against swapping the two drivers on a live system, which can wedge the dongle MCU until a power cycle.

New device page for VStarcam pan/tilt cameras (Hi3518EV200 + GC2023 MIPI + MT7601U): an install layout that keeps the vendor U-Boot (its environment at 0x80000 sits inside the kernel region of the standard layout, so standard offsets let a later saveenv corrupt the kernel), the missing-tftpdstp trap in the vendor U-Boot, GC2023 MIPI sensor notes including the digital-gain 0xb1=0 black-frame failure mode, PTZ stepper GPIOs recovered from the vendor's motogpio.ko, and the IR-cut pinmux that sysfs alone cannot reach. All verified on real hardware.

High-Level Assessment

The approach is appropriate for a wiki change: the MT7601U performance caveat is placed in the generic Wi‑Fi-driver guide (discoverable for all MT7601U users), while device-specific flashing/sensor/PTZ/IR-cut details live on a dedicated device page and are linked from the README index. Considered splitting the MT7601U content into a separate chipset troubleshooting page, but it would reduce discoverability within the existing driver selection doc without clear benefit.

Document MT7601U mainline vs STA driver performance and swap warning

• Adds a MediaTek MT7601U note explaining that mainline mt7601u and vendor-lineage mt7601sta are not equivalent on some devices. Includes measured TX throughput/latency differences and warns against swapping the drivers on a live system due to potential MCU wedging until power-cycle.
