wifi6 Linux driver - 7 - mac80211 - net/wireless

續前篇 HE - 2

修正後, 接下來遇到 reg_query_regdb_wmm()
這和這個 patch:  cfg80211: Add API to allow querying regdb for wmm_rule 有關

 +/**

+ * reg_query_regdb_wmm -  Query internal regulatory db for wmm rule
+ * Regulatory self-managed driver can use it to proactively
+ *
+ * @alpha2: the ISO/IEC 3166 alpha2 wmm rule to be queried.
+ * @freq: the freqency(in MHz) to be queried.
+ * @dbptr: pointer where the regdb wmm data is to be stored (or %NULL if
+ * irrelevant). This can be used later for deduplication.
+ * @rule: pointer to store the wmm rule from the regulatory db.
+ *
+ * Self-managed wireless drivers can use this function to  query
+ * the internal regulatory database to check whether the given
+ * ISO/IEC 3166 alpha2 country and freq have wmm rule limitations.
+ *
+ * Drivers should check the return value, its possible you can get
+ * an -ENODATA.
+ *
+ * Return: 0 on success. -ENODATA.

+int reg_query_regdb_wmm(char *alpha2, int freq, u32 *ptr,
+   struct ieee80211_wmm_rule *rule);
