[PATCH 3/5] usb: usbnet: Allow drivers using usbnet to specify maximum packet size

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The usbnet driver always attempts to set dev->maxpacket from the out
endpoint. For this to function correctly it relies on the alternate
setting containg the bulk out endpoint to be selected. This isn't
necessarily always the case.

This change allows drivers that make use of usbnet to specify the
value for dev->maxpacket themselves.
