Re: [PATCH 3.13.1 1/9] rsi: Add RS9113 driver

[Jahnavi Meher <jahnavi.meher@redpinesignals.com>]

Hi Johannes, 
Thank you for the review comments, will make the changes
as you have suggested. A-MPDU indication frames are sent 
to the firmware to start/stop tx/rx ampdu aggregation.

Regards,
Jahnavi
