[ath9k-devel] [PATCH 02/10] ath9k: Add definitions and structures to support WoW
From: Mohammed Shafi Shajakhan moham...@qca.qualcomm.com
*add structures, macros and variables for WoW, so that the driver
can make use of it.
*maintain a list for user enabled patterns and masks
*track pattern slots for the hardware limitation on the
maximum number of patterns that can be stored.
*track interrupts enabled before WoW suspend, so
that can be reconfigured after resume
*have macros to parse user defined wow configurations to
hardware code

Why do you need AH_WOW_MAX_EVENT? It looks like out of sync and also it is
never be used.
