Subject: [PATCH] net: usb: ax88179_178a: add TSO feature
|
|
|
|
On low-effciency embedded platforms, transmission performance is poor
|
|
due to on Bulk-out with single packet.
|
|
Adding TSO feature improves the transmission performance and reduces
|
|
the number of interrupt caused by Bulk-out complete.
|
|
|
|
Reference to module, net: usb: aqc111.
