Does that card support strict reset, and if so, does enabling it help? I
think the order of operations with strict reset enabled goes like:

1. Power on PC
2. Card partially initializes with pciback xen driver
3. Power on VM with pass-through NIC
4. Strict reset sent to NIC
5. Card fully initializes with VM's drivers
6. Power off VM
7. Card gets reattached to pciback

[qubes-users] RTL8111/8168/8411 requires power cycle after Windows 10

2020-08-04 Thread Ulrich Windl 

Hi!

I had reported problems with the RTL8111/8168/8411 ethernet controller 
and Qubes OS before. In the meantime I found out that it does not work 
when Windows 10 was running, and after a "restart" Qubes SO is booted.


The effect is interesting: The card detects whether the link goes up or 
down, detects the proper speed, tries DHCP, but never gets an address.


Only when I power don the PC and reboot Qubes OS, I get an address from 
DHCP.  I suspect that the card isn't fully reset when Qubes OS boots.
