I have a physical interface igb0 and a virtual link called oi0.

root@sjc3:/# dladm show-vnic
LINK OVER SPEED MACADDRESS MACADDRTYPE VID
oi0 igb0 1000 2:8:20:f:23:dc random 0

I tried to create a flow on oi0. This should work, but doesn't. What exactly is incompatible?

root@sjc3:/# flowadm add-flow -l oi0 -a transport=tcp tcpflow
flowadm: add flow failed: flow(s) with incompatible attributes exists
root@sjc3:/#

Man page:

_ The following five types of combinations of attributes are
supported:

local_ip[/prefixlen]=address
       remote_ip[/prefixlen]=address
       transport={tcp|udp|sctp|icmp|icmpv6}
       transport={tcp|udp|sctp},local_port=port
       dsfield=val[:dsfield_mask]

On  a  given  link,  the  combinations  above  are  mutually
     exclusive.  An attempt to create flows of different combina-
     tions will fail.

In fact there is even an example suggesting something similar for UDP traffic. This clearly isn't working though with TCP specified.
