Hi, ax88179_178a_rx_fixup() function is cloning the data and calling usbnet_skb_return(). Since FLAG_MULTI_PACKET is not set, usbnet_skb_return() is being called second time within rx_process() function in usbnet.c.
I simply enabled the flag in ax88179_info as below - .flags = FLAG_ETHER..| FLAG_MULTI_PACKET Ping stops working. Could anyone please point out what could be the reason behind sending same packets 2 times to upper layer (from usbnet and its class driver ax88179_178a)? In case of asix 2.0 driver, avove flag is set and it is working. Thanks, Vivek
