Have you made some pass to look for related problems on the xen-users or xen-devel mailing list or in the git commit history of mainline since 5.5.6 
was released?

If you can't find any evidence the bug has been reported or fixed already, I would encourage you to do so on the xen-devel mailing list since Linux 
4.9 won't be supported forever.

But in addition to the example configuration file, you may need to provide details about exactly what happens with 4 NICs to get a useful response. 
The output from running the xl create command, the kernel log, or the xen-hotplug log would likely contain more information.
