Hopefully the last pull request to 4.18 before the merge window.
 Nothing major here, we have smaller new features and of course a lots
 of fixes.
 
 Major changes:
 
 ath10k
 
 * add memory dump support for QCA9888 and QCA99X0
 
 * add support to configure channel dwell time
 
 * support new DFS host confirmation feature in the firmware
 
 ath
 
 * update various regulatory mappings
 
 wcn36xx
 
 * various fixes to improve reliability
 
 * add Factory Test Mode support
 
 brmfmac
 
 * add debugfs file for reading firmware capabilities
 
 mwifiex
 
 * support sysfs initiated device coredump
