bonding: show full hw address in sysfs for slave entries
[ Upstream commit 18bebc6dd3281955240062655a4df35eef2c46b3 ]
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.
