Linux 4.1.0 introduced a per-NIC IPv6 stable_secret file for RFC7217.
The stable_secret file for each NIC cannot be read until it is set,
thus LTP fails like this:
proc01 1 TFAIL : proc01.c:392: read failed:
/proc/sys/net/ipv6/conf/all/stable_secret: errno=EIO(5): Input/output error
proc01 2 TFAIL : proc01.c:392: read failed:
/proc/sys/net/ipv6/conf/default/stable_secret: errno=EIO(5): Input/output error
proc01 3 TFAIL : proc01.c:392: read failed:
/proc/sys/net/ipv6/conf/eno1/stable_secret: errno=EIO(5): Input/output error
...
Ignore the stable_secret files in the proc01 test.
TODO: A future test should verify stable_secret functionality.
