> 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 removed. The NCSI's lock should be taken when
> reading or updating its state and chained state.
> * 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.
>
> Changelog
> =========
> v2:
> * The NCSI's lock is taken when reading or updating its state as the
> {READ,WRITE}_ONCE() isn't reliable.
Series applied, thanks.
