Does FCoE require 802.1q trunking?

Since PFC in FCoE requires 802.1p CoS value, is it a requirement to use an 802.1q trunk for devices connected to a Nexus 10Gb Ethernet port?  There is a configuration command "priority-flow-control on" at the interface level.  Will this add the 802.1p value in the packet without requiring 802.1q trunking?

With FCoE, since there will be multiple VLANs on the link(for data and storage), you will need to trunk.

Thanks for the answer.  I have since found the relevant documentation regarding this configuration requirement. http://www.cisco.com/en/US/docs/switche ... on_1288667
