All 15 patches applied to the declared base 1bb784eb6e38fd73143f021608e4ef3095d0c0d7. The full kernel/modules build and focused W=1 builds for phylink.o, phy.o, ax88179.o, and ax88796b.o passed. For QEMU runtime testing I again applied Chen-Yu Tsai's `usb: xhci: Fix HCS_ERST_MAX conversion` patch. Without it, this base cannot initialize QEMU's xHCI controller. No AX88179 or PHY source was changed. The fresh functional run completed cold DHCP at 1000baseT/Full without a reload and passed the 1000/100/10/1000 Mbit/s matrix, EEE disable/restore, pause enable/restore, EEPROM read, module reload, and QEMU USB detach/reattach. Ten additional 100/full-to-1000/full cycles passed both endpoints with bound traffic and RX growth; I did not reproduce the earlier carrier-loss or carrier-without-RX failures. I also directly exercised the new phylink MII ioctl path. Read-only SIOCGMIIPHY and SIOCGMIIREG requests both succeeded and returned PHY address 3 and register 0 value 0x1040. One fresh `wol d` and three independent fresh `wol g` QEMU deep-S3 cycles all passed. Every cycle was monitor-confirmed suspended, resumed at 1000baseT/Full, and passed immediate, +10-second, and +20-second traffic/RX checks. Tested-by: Jianhui Xu Thanks, Jianhui
