Subject: net: Really remove all of LOOPBACK_TSO code.
X-Git-Tag: firefly_0821_release~16912^2~29
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3a8af722495469e9c550386b910c5b93c91cf107;p=firefly-linux-kernel-4.4.55.git

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.
