I've been trying to track down a problem where an hp dl380 gen8 with a Cavium QLogic BR-1860 Fabric Adapter is getting source-id verification failures when running dhclient against that interface. This started showing up when I backported the iova deferred flushing patches. So far this has only been seen on this one system, but I'm trying to understand why it appears with the new deferred flushing code. I also see it with both 4.18.10, and 4.19.0-rc6 kernels.
