Netgear R7800 23.05-rc2 poor gigabit network performance

The list of changes of Linux kernel 5.15 is overwhelming, please do this research by yourself: https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15

For OpenWrt 23.05 with kernel 5.15: https://openwrt.org/releases/23.05/notes-23.05.0-rc3#highlights_in_openwrt_23050

Many new devices added

OpenWrt 23.05 supports over 1794 devices. Support for over 200 new devices was added in addition to the device support by OpenWrt 22.03.

  • The ipq807x target for the Qualcomm IPQ807x Wifi 6 SoCs was added

  • The mediatek/filogic subtarget for the Mediatek Filogic 830 and 630 SoCs was added

  • The sifiveu target for the HiFive RISC-V Unleashed and Unmatched boards

Highlights of device support

  • Switched ipq40xx target to DSA

  • VDSL support on AVM FRITZ!Box 7530

  • Support for devices with 2.5G PHYs

    • Acer Predator W6 (MT7986A), Mercusys MR90X v1 (MT7986BLA), Netgear WAX206 (MT7622), Netgear WAX220 (MT7986), ZyXEL NWA50AX Pro (MT7981) Asus (TUF Gaming) AX4200 (MT7986A), Netgear WAX218 (IPQ8074), Xiaomi AX9000 (IPQ8074), Dynalink DL-WRX36 (IPQ8074)
  • 2 Gbps WAN/LAN NAT Routing on ramips MT7621 devices (See OpenWrt forum)

  • Improved DSL statistics on ubus and in LuCI

The support for ipq807x Qualcomm AX and Mediatek Filogic 830 AX for me alone is worth this update. 2.5 Gbps Ethernet will be a benefit for users with more than 1 Gbps needs.
