   4 Subject: [PATCH] wifi: rtw88: usb: Enable switching the RTL8814AU to USB 3
   5
   6 The Realtek wifi 5 devices which support USB 3 are weird: when first
   7 plugged in, they pretend to be USB 2. The driver needs to send some
   8 commands to the device, which make it disappear and come back as a
   9 USB 3 device.

  11 The method used to switch the RTL8812AU also works for the RTL8814AU.
