REALTEK RTL8127 MacOS驱动(0.2.29)

• 软件描述：RTL8127 beta3: signed DriverKit driver for Apple Silicon, macOS 27 aware (0.2.29)
  RTL8127 / RTL8127ATF 10GbE support for Apple Silicon Macs, as a signed and
  notarized DriverKit extension. Download RTL8127-0.2.29.pkg, run it, approve
  the driver once in System Settings, plug the card in. No recoveryOS, no
  Reduced Security, no csrutil changes.
  
  beta3 is the first release aware of macOS 27, which ships its own
  Realtek driver (see below). It installs and runs on macOS 26 too; the
  driver is the same as in beta2 (0.2.27), only the app changed. beta2 stays
  available for people who want to keep the macOS 26 behaviour.
  
  Validated on hardware (M5 Mac, macOS 26.6, RTL8127ATF SFP+ in a
  Thunderbolt enclosure, DAC to a 10G switch, Linux iperf3 peer):
  
  Test MTU 1500 MTU 9000
  TX, 1 stream 9.40 Gbit/s 9.63 Gbit/s
  RX, 1 stream 9.38 Gbit/s 9.89 Gbit/s
  TX, 4 streams 9.22 Gbit/s 9.65 Gbit/s
  RX, 4 streams 9.39 Gbit/s 9.89 Gbit/s
  TX, 8 streams 4.5 Gbit/s 9.71 Gbit/s
  RX, 8 streams 9.39 Gbit/s 9.77 Gbit/s
  DHCP, IPv4/IPv6, multicast (mDNS/Bonjour), Network.framework and BSD socket
  traffic, TCP segmentation offload (IPv4/IPv6), checksum offload, jumbo frames
  up to 9000, all exercised on the card.
  
  What is in the package
  
  RTL8127App.app (Applications): installs and removes the driver, shows
  card detection, driver state and link, in English, French, German, Spanish,
  Italian, Japanese and Simplified Chinese.
  net.wizzz.RTL8127Dext.dext inside it: the DriverKit driver, Developer ID
  signed, notarized, stapled.
  macOS 27 (0.2.29, 10 Oct 2026): macOS 27 ships its own driver for the
  Realtek RTL8125/8126/8127 (AppleEthernetRL): line rate, no jumbo frames
  (MTU capped at 1500), takes the card at every boot and cannot be displaced
  from user space. The app now detects it. On macOS 27 and later a fresh
  install leaves the card to the macOS driver and offers "Use this driver
  instead"; a Mac upgraded from macOS 26 gets a one-time choice. If you pick
  this driver, unplug and replug the card once after each boot; the app
  checks at login and posts a notification when that is needed. New
  "Uninstall completely" button (driver, login item, settings and app). The
  driver itself is unchanged since 0.2.27.
  
  Fixed in 0.2.27 (14 Sept 2026): RTL8127 RJ45 (10GBASE-T) cards linked
  at 5G only. The PHY code inherited from the RTL8125/8126 driver never
  advertised 10GBASE-T during auto-negotiation; it now does, like Realtek's
  r8127 Linux driver. Reported by a board vendor's macOS test; not yet
  re-tested on a copper card (the SFP+ path is unchanged). If you have an RJ45
  RTL8127, please try it and open a hardware report.
  
  Fixed in 0.2.26 (13 Sept 2026): Energy Efficient Ethernet was left
  enabled on the SFP+ SerDes link (the kext and Realtek's Linux driver keep
  it off there). Symptoms: a steady trickle of rx CRC errors when the link
  was idle and a 1-2 s link drop every 20-40 minutes. EEE is now off. A link
  drop is also confirmed by a second PHY read before the chip is reset.
  
  Fixed in 0.2.23 (13 Sept 2026, replaces the 0.2.22 package first
  published under this tag): reception stopped for good after the link
  dropped and came back (a 1-2 s link flap on the DAC or switch), until the
  card was replugged. The chip is soft-reset on every link drop and restarts
  its rx ring at descriptor 0; the driver now restarts both rings with it, and
  a 5-second safety net re-arms the rx ring if reception ever stalls again.
  If you installed 0.2.22, run the new package; the card may need a replug
  once to switch to the new driver instance.
  
  Changes since beta1 (kext-only, June 2026)
  
  DriverKit port of the RTL8127 driver: hardware layer shared verbatim with
  the kext, NetworkingDriverKit datapath with four TX queues (service
  classes), TSO4/6, checksum offload, multicast hash filter, kext-style
  interrupt mitigation, hardware statistics.
  Signed with Apple's DriverKit entitlements (PCI transport, networking
  family), notarized installer package.
  Kext: RX length field read on 14 bits (frames over 8191 bytes were
  truncated). The kext is no longer shipped in releases; build it from
  source if you need it.
  README rewritten as an install guide, issue templates (hardware reports),
  benchmark tool in tools/.
  Known limitations
  
  Eight or more parallel TCP streams sending from the Mac at MTU 1500 top
  out around 4.5 Gbit/s (per-packet cost in the dext). Not an issue at MTU
  9000 or with up to four streams.
  Link medium displayed as 10GBase-T over SFP+/DAC (cosmetic).
  RTL8127A (RJ45) path ported but untested. Reports welcome.
  No Wake on LAN. tcpdump only sees kernel-path traffic (the BPF tap API
  panics macOS 26 inside IOSkywalkFamily, so it is not used).
  Upgrading from an earlier 0.2.x package: run the pkg; if the card does
  not come back, unplug and replug it (the previous driver instance can hold
  the device until then).
