Subject: [PATCHv2 net 0/4] bonding: fix send_peer_notif overflow

Bonding send_peer_notif was defined as u8. But the value is
num_peer_notif multiplied by peer_notif_delay, which is u8 * u32.
This would cause the send_peer_notif overflow.

Before the fix:
TEST: num_grat_arp (active-backup miimon num_grat_arp 10)           [ OK ]
TEST: num_grat_arp (active-backup miimon num_grat_arp 20)           [ OK ]
4 garp packets sent on active slave eth1
TEST: num_grat_arp (active-backup miimon num_grat_arp 30)           [FAIL]
24 garp packets sent on active slave eth1
TEST: num_grat_arp (active-backup miimon num_grat_arp 50)           [FAIL]

After the fix:
TEST: num_grat_arp (active-backup miimon num_grat_arp 10)           [ OK ]
TEST: num_grat_arp (active-backup miimon num_grat_arp 20)           [ OK ]
TEST: num_grat_arp (active-backup miimon num_grat_arp 30)           [ OK ]
TEST: num_grat_arp (active-backup miimon num_grat_arp 50)           [ OK ]
