Unable to achieve "Increased bandwidth" with DLMP on Solaris 11.4

Hi All,
I recently created DLMP link aggregation on Solaris 11.4, 11.4-11.4.34.0.1.94.4.
The link failover working perfectly but the bandwidth increase not achieved as only one physical card is transmitting and receiving network packets at one time. Here is my configuration:  

 

Have three network cards

root@S11-RepoServer:~# dladm show-phys -Z

LINK            ZONE      MEDIA         STATE      SPEED  DUPLEX    DEVICE

net0            global    Ethernet      up         0      unknown   vnet0

net1            global    Ethernet      up         1000   full      ixgbe0

net2            global    Ethernet      up         1000   full      ixgbe1
