usbnet(4) — generic USB network driver backend diagnostics 💅

Okay so bestie, this is the manual page for usbnet(4), and it’s literally all about the generic USB network driver backend diagnostics. Slay.

💖 DESCRIPTION 💖

The usbnet subsystem provides support for USB network devices. This manual describes the diagnostics that may be seen. Lowkey essential info, no cap. 🫶

🔥 DIAGNOSTICS 🔥

Here’s the full vibe check on every diagnostic, fr fr:

• devN: sysctl_createv failed — it was unable to create the debug node for NetBSD. 😭
• devN: usb errors on rx — there’s an error status from the device upon the Rx interrupt, and the device may be non-functional.
• devN: usb error on tx — there’s an error status from the device upon the Tx interrupt, and the device may be non-functional.
• devN: usb error on intr — there’s an error status from the device upon interrupt, and the device may be non-functional.
• devN: rxeof: too large transfer — network input was rejected. 🙈
• devN: close pipe N — closing of the Rx, Tx or Interrupt pipe failed, and the device may be non-functional.
• devN: open rx/tx pipes failed — opening of the Rx or Tx pipes failed, and the device is non-functional.
• devN: [rt]x list init failed — creation of the Rx or Tx list failed, and the device is non-functional.
• devN: watchdog timeout — there was a time out in transmission. ⏰
• devN: pipe abort failed — aborting USB pipes after a watchdog timeout failed.
• devN: couldn't establish power handler — the call to pmf_device_register(9) failed, and this disables system suspend.

The usbnet manual lists generic diagnostics generated by USB network devices. That’s the whole point, bestie. 💖
