Subject: [PATCH next v4 2/3] ipvlan: mode is u16

From: Mahesh Bandewar <maheshb@...gle.com>

The mode argument was erronusly defined as u32 but it has always
been u16. Also use ipvlan_set_mode() helper to set the mode instead
of assigning directly. This should avoid future erronus assignments /
updates.
