Hi Jesse,

The backport of fac8e0f579695a3ecbc4d3cac369139d7f819971,
"tunnels: Don't apply GRO to multiple layers of encapsulation",
to linux-4.1.y seems to have missed a line.

The 4.1 commit is 066b300e5be43cb61697539e2a3a9aac5afb422f.

The potentially missing line is:

-               .gro_receive    = ipv6_gro_receive,
+               .gro_receive    = sit_gro_receive,


I am not experiencing any bad symptoms.  I simply noticed
that the patch introduced a new function, sit_gro_receive,
without introducing any users, and that same patch in  
linux-4.4.y does have a user.

Regards,
Joe
