hsr: add hsr root debugfs directory
In current hsr code, when hsr interface is created, it creates debugfs directory /sys/kernel/debug/<interface name>. If there is same directory or file name in there, it fails. In order to reduce possibility of failure of creation of debugfs, this patch adds root directory. Test commands: ip link add dummy0 type dummy ip link add dummy1 type dummy ip link add hsr0 type hsr slave1 dummy0 slave2 dummy1 Before this patch: /sys/kernel/debug/hsr0/node_table After this patch: /sys/kernel/debug/hsr/hsr0/node_table Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S.
