Subject: [PATCH 5/5] usb: cdc-ncm: Allow NCM driver to determine dev->maxpacket

As the NCM driver does not necessarily select the alternate setting
which presents the data bulk endpoints, dev->maxpacket can't be set
correctly by usbnet.

This fixes this by getting the NCM driver to set the dev->maxpacket itself.
