Merge branch 'ncsi-next'
Gavin Shan says: ==================== net/ncsi: NCSI Improvment and bug fixes 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
