Hi, thank you for your suggestion. I have a question about usb2eth. In the function gen_ndis_set_resp of the rndis.c, the value of *params->filter may be 0x20 from the pc set command; Howerver the value is used cdc_filter = dev->port_usb->cdc_filter in the function eth_start_xmit of the u_ether.c. If we do not judge the RNDIS_PACKET_TYPE_PROMISCUOUS and the value is 0x20, the broadcast packet can not send the pc win7; At the result, the linux ping the win7 is slow an the first. At the same time, Why are different value between RNDIS_PACKET_TYPE_PROMISCUOUS and USB_CDC_PACKET_TYPE_PROMISCUOUS? If the value of RNDIS_PACKET_TYPE_PROMISCUOUS and USB_CDC_PACKET_TYPE_PROMISCUOUS is same, then the linux ping the win7 is normal speed.
