The function cdns3_ep_config() calculates the maximum packet size based on the Endpoint Type and the Gadget Speed and stores it in the variable "max_packet_size". This value is then programmed in the USB Controller for the corresponding Endpoint. This may result in a mismatch between the maximum packet size programmed in the USB controller and the maximum packet size seen by the UDC Core via "maxpacket" member of "struct usb_ep". Additionally, since TD_SIZE is calculated in cdns3_ep_run_transfer() on the basis of the maximum packet size stored in the "maxpacket" member of "struct usb_ep", it may lead to an incorrect value of TD_SIZE when compared with what the USB controller actually expects (max_packet_size).
