That shouldn't matter, since the PHY gets reset after that anyway, and the final PHY status in both screenshots is the same (0x93 = 1000Mbps full-duplex, as expected).

Could you try building with DEBUG=realtek:3, and observe network traffic in real-time using tcpdump or wireshark? The extra debug will show you messages for each transmitted and received packet, and tcpdump/wireshark will allow you to see what's actually happening on the wire. It would be interesting to know if, for example, the failure case involves iPXE being able to transmit packets which show up on the wire, but not being able to receive anything.

It would also be good to know if the link status lights on the switch agree with the link status as reported by iPXE via the debug messages. I've just pushed an extra commit which adds an explanation of the PHY status register value to the debug messages.
