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

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