zfsiostats.py and cache

[sersim]

If I have cache devices in my ZFS storage pool I get errors:
2015-10-28 21:20:34,887 tcollector[14141] WARNING: zfsiostats.py: File ".../tcollector/collectors/0/zfsiostats.py", line 167, in main
2015-10-28 21:20:34,887 tcollector[14141] WARNING: zfsiostats.py: "expecting last state T_SEPARATOR, now got %s" % ltype
2015-10-28 21:20:34,887 tcollector[14141] WARNING: zfsiostats.py: AssertionError: expecting last state T_SEPARATOR, now got 5

Looks like it doesn't expect to find the cache section

My workaround is adding these lines:
elif line.startswith("cache"):
assert ltype in (T_POOL, T_DEVICE),
"expecting last state T_POOL or T_DEVICE, now got %s" % ltype
ltype = T_LEG
