Hello, I'm encountering the exact same problem (same model of machine, same controller, same OS) and was wondering where this bug was at.
I just used my Ethernet NIC for the first time on an up-to-date Archlinux; it was working fine until I suspended to RAM: on resume the Realtek/Ethernet device had completely disappeared. The two entries absent from lspci output after resume are: $ sudo lspci -v (…) 03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Tell me whether my dmesg may be of any use, but I doubt it as it is pretty close to original poster's one.
