/**
 * DOC: wlan_pmo_wowl
 *
 * This module houses all the logic for WOW(wake on wireless) in
 * PMO(Power Management and Offload).
 *
 * It provides the following APIs
 *
 * - Ability to enable/disable following WoWL modes
 *  1) Magic packet (MP) mode
 *  2) Pattern Byte Matching (PBM) mode
 * - Ability to add/remove patterns for PBM
 *
 * A Magic Packet is a packet that contains 6 0xFFs followed by 16
 * contiguous copies of the receiving NIC's Ethernet address. There is
 * no API to configure Magic Packet Pattern.
 *
 * Wakeup pattern (used for PBM) is defined as following:
 * struct
 * {
 *  U8  PatternSize;                  // Non-Zero pattern size
 *  U8  PatternMaskSize;              // Non-zero pattern mask size
 *  U8  PatternMask[PatternMaskSize]; // Pattern mask
 *  U8  Pattern[PatternSize];         // Pattern
 * } hdd_wowl_ptrn_t;
 *
 * PatternSize and PatternMaskSize indicate size of the variable
 * length Pattern and PatternMask. PatternMask indicates which bytes
 * of an incoming packet should be compared with corresponding bytes
 * in the pattern.
 *
 * Maximum allowed pattern size is 128 bytes. Maximum allowed
 * PatternMaskSize is 16 bytes.
 *
 * Maximum number of patterns that can be configured is 8
 *
 * PMO will add following 2 commonly used patterns for PBM by default:
 *  1) ARP Broadcast Pattern
 *  2) Unicast Pattern
 *
 * However note that WoWL will not be enabled by default by PMO. WoWL
 * needs to enabled explcitly by exercising the iwpriv command.
 *
 * PMO will expose an API that accepts patterns as Hex string in the
 * following format:
 * "PatternSize:PatternMaskSize:PatternMask:Pattern"
 *
 * Multiple patterns can be specified by deleimiting each pattern with
 * the ';' token:
 * "PatternSize1:PatternMaskSize1:PatternMask1:Pattern1;PatternSize2:..."
 *
 * Patterns can be configured dynamically via iwpriv cmd or statically
 * via qcom_cfg.ini file
 *
 * PBM (when enabled) can perform filtering on unicast data or
 * broadcast data or both. These configurations are part of factory
 * default (cfg.dat) and the default behavior is to perform filtering
 * on both unicast and data frames.
 *
 * MP filtering (when enabled) is performed ALWAYS on both unicast and
 * broadcast data frames.
 *
 * Management frames are not subjected to WoWL filtering and are
 * discarded when WoWL is enabled.
 *
 * Whenever a pattern match succeeds, RX path is restored and packets
 * (both management and data) will be pushed to the host from that
 * point onwards.  Therefore, exit from WoWL is implicit and happens
 * automatically when the first packet match succeeds.
 *
 * WoWL works on top of BMPS. So when WoWL is requested, SME will
 * attempt to put the device in BMPS mode (if not already in BMPS). If
 * attempt to BMPS fails, request for WoWL will be rejected.
