Thanks, these are vr interfaces which do not support TSO.  Also, its
pure forwarding that seems to be the issue and I dont think TSO enters
into that ?

vr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8280b<RXCSUM,TXCSUM,VLAN_MTU,WOL_UCAST,WOL_MAGIC,LINKSTATE>
        ether 00:0d:b9:1c:60:48
        inet 192.168.xx.xx netmask 0xffffff00 broadcast 192.168.xx.xx
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
