bonding: show full hw address in sysfs for slave entries
Bond expects ethernet hwaddr for its slave, but it can be longer than 6 bytes - infiniband interface for example. # cat /sys/devices/<skipped>/net/ib0/address 80:00:02:08:fe:80:00:00:00:00:00:00:7c:fe:90:03:00:be:5d:e1 # cat /sys/devices/<skipped>/net/ib0/bonding_slave/perm_hwaddr 80:00:02:08:fe:80 So print full hwaddr in sysfs "bonding_slave/perm_hwaddr" as well.
