Subject: [PATCH Resend] net: asix: add missing flag to struct driver_info

The struct driver_info ax88178_info is assigned the function
asix_rx_fixup_common as it's rx_fixup callback. This means that
FLAG_MULTI_PACKET must be set as this function is cloning the
data and calling usbnet_skb_return. Not setting this flag leads
to usbnet_skb_return beeing called a second time from within
the rx_process function in the usbnet module.
