This patch may work on ixgbe, but I am using i40e and the message is still present. I tried to apply your logic above and that seemed to fix the i40e message.

Looks like you need to change all of the drivers that use this logic.

Here is the i40e change:

i40e_dev_start()
-    if (!pf->tm_conf.committed)
+    if (pf->tm_conf.root && !pf->tm_conf.committed)
