Thanks for pointing this out, I've commited the following to
correct it.

commit 3a8af722495469e9c550386b910c5b93c91cf107
Author: David S. Miller <davem@davemloft.net>
Date:   Fri Oct 31 00:00:33 2008 -0700

    net: Really remove all of LOOPBACK_TSO code.
    
    As noticed by Saikiran Madugula, commit 7447ef63cf2dfdc444f4c72ae13f604350b2e25f
    ("loopback: Remove rest of LOOPBACK_TSO code.") got rid of
    emulate_large_send_offload() but didn't get rid of the call
    site as well.
