Well I thought this was done but just made a discovery: out of curiosity, I disabled Native ASPM in the BIOS on my mobo and upon rebooting my server found that ASPM shows as enabled on all my devices! I am still using the native Realtek driver, R8169, and see no loss in speeds in docker or in iperf3. That being said, I'm still stuck at C3 once my drives spin down. I then installed the R8125 driver plugin, added the r8125.conf file to /boot/config/modprobe.d, and the speed issues persist.  I am marking this new entry as the solution because ultimately, I will need an updated Realtek driver for the lower C states to be possible.

Thanks to some support by @1812, I've got a working 10GbE port for my VM and Unraid server. His recommendation was to establish the open Solarflare port as the primary NIC. This solution has allowed to me to use that 10GbE port as the network interface for Unraid. That being said, if I make any changes to the network config for it in the UI, IP, VLAN, etc. , it kernel panics like it has been. However, the network settings persist upon reboot so after manually editing the config on another computer and working through a couple kernel panics and hard resets, I have a 10GbE port for my server. Something else really cool: when I iperf3 between the port passed through to my VM and the port on my server, I get over 20Gbits/sec. Awesome.
