- aes67_board: Waveshare ESP32-P4-ETH pin profile and EMAC + IP101 driver install (PHY addr 1, reset GPIO51, ref clock in on GPIO50). - aes67_net: Ethernet netif with DHCP client; logs link up/down (speed, duplex, MAC) and the DHCP lease. - Verified on board: 100 Mbps full duplex, DHCP lease in ~8 s, ping 0% loss, ~0.2 ms RTT.
