+Subject: [PATCH 21/21] updating minimum firmware requirement
+
+This patch mandates the driver to work with firmware version
+8.9.0.0.83 or above.
+This is to fix kernel panic caused by establishing a PMF/WPA3
+connection using older firmware versions
+
+Latest firmware is available at:
+git://git.ti.com/wilink8-wlan/wl18xx_fw.git
