This series of patches improves NCSI stack according to the comments
I received after the NCSI code was merged to 4.8.rc1:
* PATCH[1/8] fixes the build warning caused by xchg() with ia64-linux-gcc.
The atomic operations are replaced with {READ, WRITE}_ONCE().
* Channel ID (0x1f) is the reserved one and it cannot be valid channel ID.
So we needn't try to probe channel whose ID is 0x1f. PATCH[2/8] and
PATCH[3/8] are addressing this issue.
* The request IDs are assigned in round-robin fashion, but it's broken.
PATCH[4/8] make it work.
* PATCH[5/8] and PATCH[6/8] reworks the channel monitoring to improve the
code readability and its robustness.
* PATCH[7/8] and PATCH[8/8] introduces ncsi_stop_dev() so that the network
device can be closed and opened afterwards. No error will be seen.
