There are differences, they are quite slight. Most focus around the branding and the XenServer specific platform device. A few changes are specific to XenServer usecases which make no sense for Xen.
XenServer drivers lag behind the bleeding edge of the Xen drivers for stability reasons. In general Citrix upstream fixes for issues found to the bleeding edge drivers straight away, but may then backport them to older branches to address
customer specific issues without pushing that change upstream.
Also XenServer drivers have a lot of automated testing vs XenServer. The Xen drivers benefit from this in terms of getting the fixes, but not in terms of testing how well they work with non-XenServer builds of Xen.
So XenServer drivers are likely to be slightly more stable than Xen drivers of a similar version – and probably much more stable when used in conjunction with XenServer. But there isn’t much in it, if you stick to the same major and minor versions.

Hello.
Is there any difference between xenbits and closed source Citrix xenserver drivers (BSD licence allows it) ?
Are Citrix drivers more stable and more faster (eg. intentionally blocking
upstream updates to xenbits repository) ?
Citrix "updates" xenserver drivers over "Windows Update (WSUS)" (only if
you have Citrix "Enterprise+" license) ( https://www.citrix.com/content/dam/citrix/en_us/documents/product-overview/citrix-xenserver-feature-matrix.pdf ).
How is it possible to do that (I suppose it is using different PCIE VID/PID) ?
Thanks for clarification, Martin
PS: from XenServer-7.3.0-source.iso -> /SPackages/xenserver-pv-tools-7.21.0-1.src.rpm
-> /xenserver-pv-tools-7.21.0/urls/windows/xenserver/tools ->
https://repo.citrite.net:443/xs-local-build/win-installer/master/win-installer-1119/installer-new.tar
does not work (repo.citrite.net not accessible from internet).
