2013-11-15net: ethernet: ti/cpsw: do not crash on single-MAC machines during resumeDaniel Mack

2013-11-15bonding: add ip checks when store ip targetWang Weidong
I met a Bug when I add ip target with the wrong ip address: echo +500.500.500.500 > /sys/class/net/bond0/bonding/arp_ip_target the wrong ip address will transfor to 245.245.245.244 and add to the ip target success, it is uncorrect, so I add checks to avoid adding wrong address. The in4_pton() will set wrong ip address to 0.0.0.0, it will return by the next check and will not add to ip target. v2 According Veaceslav's opinion, simplify the code. v3 According Veaceslav's opinion, add broadcast check and make a micro definition to package it. v4 Solve the problem of the format which David point out.
