usbnet: changes for upcoming cdc_ncm driver
Changes: include/linux/usb/usbnet.h: - a new flag to indicate driver's capability to accumulate IP packets in Tx direction and extract several packets from single skb in Rx direction. drivers/net/usb/usbnet.c: - the procedure of counting packets in usbnet was updated due to the accumulating of IP packets in the driver - no short packets are sent if indicated by the flag in driver_info structure Signed-off-by: Alexey Orishko <alexey.orishko@stericsson.com> Signed-off-by: David S.
