ixgbe: SR-IOV: dynamic IEEE DCBx default priority changes
IEEE DCBx has a mechanism to change the default user priority. In
the normal case the OS can handle this via cgroups, iptables, socket,
options etc.
With SR-IOV and direct assigned VF devices the default priority
needs to be set by the PF device so the inserted VLAN tag is
correct.
