Here the backporting process has to work differently.

Since the fixed code is also present in the master branch of the tree
responsible with bug fixes for this code area
(https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git), you
have to base your patch on that tree, and send the patch to be applied
by the netdev maintainers, not by stable directly. You do that by using
git send-email --subject-prefix "PATCH v2 net". You also don't CC stable
and Greg, just the networking people from ./scripts/get_maintainer.pl.
After a while, the patch will land automatically in stable, through the
"net" tree.

You must also add this above your Signed-off-by tag:
