This series provides fixes for the ASIX AX88179A Ethernet driver in
U-Boot, addressing issues with PHY hang and stalling when handling
large fragmented packets on the ASIX AX88179A variant.

v1 -> v2:
    - Fix PHY reset and auto-negotiation restart logic
    - Remove ADVERTISE_NPAGE bit from MII_ADVERTISE register
    - Add reproduction steps for large fragmented packet stall
    - Adjust AX_RX_URB_SIZE to align with updated bulk-in size

Tested on a Raspberry Pi 3 Model B V1.2 with the following adapters:

 - Hiearcool USB C Hub with Gigabit Ethernet (UCN3610) - ASIX AX88179A
