openwrt/package/kernel/mac80211/patches/020-19-rt2x00-add-support-for-MT7620.patch
Daniel Golle 5b91d2b52e mac80211: rt2x00: import upstream changes and rebase our patches 
Some of our local patches have been accepted upstream. And there are
some more relevant changes (mostly for rt2800usb). Import them and
rebase our remaining local patches on top.

Subject: [PATCH 19/19] rt2x00: add support for MT7620
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.
