I take it back. I was led to believe things were working in the past. In 
fact, the difference is that F20 refuses to do the ping whereas earlier 
versions complained and then fell back to pinging from the interface 
address.

F20: # ping -I eth3:sub1 172.17.30.1
      ping: SO_BINDTODEVICE: Invalid argument

F14: # ping -I eth3:sub1 172.17.30.1
      Warning: cannot bind to specified iface, falling back: No such device
      PING 172.17.30.1 (172.17.30.1) from 172.17.30.161 eth3:sub1:
      64 bytes from ...

Sorry for the confusion.
