This is definitely r8169 - RealTek RTL-8169 Gigabit Ethernet driver defect.
I tested with a variety of kernels starting with 3.10.0-123.9.3.el7.x86_64 up to the latest 3.18 series.
For example, skge - SysKonnect Gigabit Ethernet driver and rt2800usb - Ralink RT2800 USB Wireless LAN driver do not suffer from this issue.
The problem arises when cloned-mac-address is used, and to actually recover connection after 'thaw' there is no need to reload module per se
i.e. 'modprobe -rv r8169 && modprobe -v r8169'
it is sufficient to re-apply cloned-mac-address
i.e. 'ifconfig enp3s0 hw ether 00:12:34:56:78:30'
or use some other equivalent method.
Nevertheless this is broken behavior.
If you have an idea how to solve this within module or if you have a patch, don't hesitate to ping.
