I have similar setup with 10GE Intel NIC on bare-metal box running Ubuntu
18.10. I don’t see such an issue in the past up to the current VPP being used
which is 19.04 (unless something changed with 19.08 or master). The 10GE port
is connected to an IXIA tester and when I set interface state down, the IXIA
port also goes to the down state. See the following output from VPP CLI which
shows the link in carrier down/up state according to the “set interface state
..” CLI:

Subject: [vpp-dev] Regarding "set interface state down"
Hello,
For a physical interface , say 1 Gig or 10 Gig, it looks like the command "set
interface state TenGig0/x down", does not bring down the physical link as
well, apart from the interface admin-state, so the remote peer does not
actually sense a link down. This is for IXGBE driver, and bare-metal box. (not
a VM)
Is it fair to be surprised, what is the expected way to handle this. Should it
be always be via link-state advertisement protocols.
Thanks,
Milan
