Label eth0 with a MCS security category?

In FC-11, under the targeted policy, is it possible to label an ethernet interface (such as eth0, eth1) with a specific MCS category? Example: 1) Use semanage to assign user1 to s0:c5 3) Assign eth0 to s0:c4 (Can this be done?) 4) Assign eth1 to s0:c5 Desired result: if user1 tries to ping -I eth1 <ip_address> the ping command will work (as both eth1 and user1 have category c5). If user1 tries to ping -I eth0 <ip_address>, the ping command will not work (category mismatch between user and eth1).
