Subject: [PATCH net-next v2 03/25] bonding: convert packets_per_slave to use the new option API
This patch adds the necessary changes so packets_per_slave would use the
new bonding option API.
Signed-off-by: Nikolay Aleksandrov <nikolay@...hat.com>

v2: rebase on the changes that got in while waiting and use the new code
