I have a virtual nic (vnic) on oi_148

  dladm create-vnic -m random -l igb0 vnic2
  ipadm create-addr -T static -d -a 192.168.11.127/24 vnic2/test

Interface igb0 has an IP of the same subnet of vnic2

Whitout VNIC, outgoing packets have the igb0 ip address. Ok.

With VNIC configured and enabled, outgoing packets have the vnic2 ip
address.

If I add a second vnic, outgoing packets will have the ip address of
such second vnic.

The routing table is as follow

  netstat -nr

Routing Table: IPv4
  Destination           Gateway           Flags  Ref     Use  Interface
-------------------- -------------------- ----- ----- ----------------
default              192.168.11.1           UG      7   10763
192.168.11.0         192.168.11.127         U       3   3033 vnic2
192.168.11.0         192.168.11.50          US      7   8224 igb0
127.0.0.1            127.0.0.1            UH        2   168  lo0


There is a way to set priority or precedence?
Even if I use ifconfig vnic2 deprecated, as stated in the man page,
outgoing packets have vnic2 ip address as source ip.
