REALTEK RTL8127 MacOS驱动

• 软件描述：RTL8127 / RTL8127ATF 10GbE support for Apple Silicon Macs, as a signed and
  notarized DriverKit extension. Download , run it, approve
  the driver once in System Settings, plug the card in. No recoveryOS, no
  Reduced Security, no changes.RTL8127-0.2.27.pkgcsrutil
  
  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.
  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/
  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.
  
  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.
  
  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).
