Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

Smooth Cong Wang's bug fix into 'net-next'.  Basically put
the bulk of the tcf_block_put() logic from 'net' into
tcf_block_put_ext(), but after the offload unbind.

@ -211,9 +211,7 @@ Description:
device, after it has been suspended at run time, from a resume
request to the moment the device will be ready to process I/O,
in microseconds. If it is equal to 0, however, this means that
the PM QoS resume latency may be arbitrary and the special value
"n/a" means that user space cannot accept any resume latency at
all for the given device.
the PM QoS resume latency may be arbitrary.
Not all drivers support this attribute. If it isn't supported,
it is not present.
