    mac80211: ath11k: fix for unsupported 11ax EDCA
    
    Currently publicly available firmware for ath11k does not support
    the 11ax EDCA parameter.
    Skipping sending this parameter allows the use of STA mode.

+Subject: [PATCH] wifi: ath11k: Fix the WMM param type
+
+Since FW does not support the 11ax EDCA parameter in WMI TLV command.
+FW was crashing as host was sending this parameter, now changed the
+WMM parameter type as default zero before sending to FW.
