bonding: fix send_peer_notif overflow
[ Upstream commit 9949e2e ] Bonding send_peer_notif was defined as u8. Since commit 07a4dde ("bonding: add an option to specify a delay between peer notifications"). the bond->send_peer_notif will be num_peer_notif multiplied by peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif overflow easily. e.g. ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000 To fix the overflow, let's set the send_peer_notif to u32 and limit peer_notif_delay to 300s.
