2.22.1-1

What's Changed

The vendor base-code changes below were summarized by Claude Code (AI) from a source diff, not an official Realtek changelog.

• The base code has been updated to version 2.22.1, which includes the following changes:
  • New device support: differentiates RTL8159 QFN68/QFN100 packages via a new PLA_PKG_DET register read, and adds ASUSTek USB ID 0x1d91.
  • RTL8159 (QFN68) firmware/PHY updates: new USB patch code, RAM code bumped to 0x0022, and several PHY tuning changes (CLKS latency, PLL jitter, power level).
  • Per-speed EEE support (100M/1G/2.5G/5G/10G) for Ultra Power Save flags.
  • Power management rework: new UPS enable/disable flow for RTL8157/RTL8159.
  • Fixed a false TX-watchdog timeout by updating the netdev trans_start timestamp on every successful TX submission.
  • Fixed a potential resource leak by dropping packets immediately when the link is down instead of queuing them.
  • Worked around an ASMedia ASM2142 host-controller firmware freeze by disabling scatter-gather DMA under that controller.
  • Fixed a flow-control pause-packet bug where the option flag for certain chip versions was inverted.
  • Added 32-bit compat ioctl support, so rtltool-based utilities work correctly from 32-bit userspace on a 64-bit kernel.
  • Various suspend/resume ordering fixes and additional debug logging.
