+Subject: [PATCH 37/73] mwifiex: correction in mcs index check
+
+commit fe020120cb863ba918c6d603345342a880272c4d upstream.
+
+mwifiex driver supports 2x2 chips as well. Hence valid mcs values
+are 0 to 15. The check for mcs index is corrected in this patch.
+
+For example: if 40MHz is enabled and mcs index is 11, "iw link"
+command would show "tx bitrate: 108.0 MBit/s" without this patch.
+Now it shows "tx bitrate: 108.0 MBit/s MCS 11 40Mhz" with the patch.
