+Subject: [PATCH] mac80211: rt2x00: add support for MT7620
+To: Stanislaw Gruszka <sgruszka@redhat.com>
+Cc: Helmut Schaa <helmut.schaa@googlemail.com>,
+ linux-wireless@vger.kernel.org,
+ Kalle Valo <kvalo@codeaurora.org>
+
+From: Roman Yeryomin <roman@advem.lv>
-Support for MT7620 was added to OpenWrt in r41441 and heavily reworked
+Basic support for MT7620 built-in wireless radio was added to
+OpenWrt in r41441. It has seen some heavy cleaning and refactoring
since in order to match the Kernel's code quality standards.
