What a coincidence. I've been slowly working on porting r8152 driver from Linux to FreeBSD since last month. > Some more details on the device: > [root@vbsd101 /usr/src]# usbconfig -d ugen1.2 dump_device_desc > ugen1.2: <USB 10100 LAN Realtek> at usbus1, cfg=0 md=HOST spd=HIGH > (480Mbps) pwr=ON (100mA) > > bLength = 0x0012 > bDescriptorType = 0x0001 > bcdUSB = 0x0210 > bDeviceClass = 0x0000 > bDeviceSubClass = 0x0000 > bDeviceProtocol = 0x0000 > bMaxPacketSize0 = 0x0040 > idVendor = 0x0bda > idProduct = 0x8152 > bcdDevice = 0x2000 > iManufacturer = 0x0001 <Realtek> > iProduct = 0x0002 <USB 10/100 LAN> > iSerialNumber = 0x0003 <64D1A3318180> > bNumConfigurations = 0x0002 > > > > [root@vbsd101 /usr/src]# usbconfig -d ugen1.2 dump_all_config_desc > ugen1.2: <USB 10100 LAN Realtek> at usbus1, cfg=0 md=HOST spd=HIGH > (480Mbps) pwr=ON (100mA) > > > Configuration index 0 > > bLength = 0x0009 > bDescriptorType = 0x0002 > wTotalLength = 0x0027 > bNumInterfaces = 0x0001 > bConfigurationValue = 0x0001 > iConfiguration = 0x0000 <no string> > bmAttributes = 0x00a0 > bMaxPower = 0x0032 > > Interface 0 > bLength = 0x0009 > bDescriptorType = 0x0004 > bInterfaceNumber = 0x0000 > bAlternateSetting = 0x0000 > bNumEndpoints = 0x0003 > bInterfaceClass = 0x00ff > bInterfaceSubClass = 0x00ff > bInterfaceProtocol = 0x0000 > iInterface = 0x0000 <no string> > > Endpoint 0 > bLength = 0x0007 > bDescriptorType = 0x0005 > bEndpointAddress = 0x0081 <IN> > bmAttributes = 0x0002 <BULK> > wMaxPacketSize = 0x0200 > bInterval = 0x0000 > bRefresh = 0x0000 > bSynchAddress = 0x0000 > > Endpoint 1 > bLength = 0x0007 > bDescriptorType = 0x0005 > bEndpointAddress = 0x0002 <OUT> > bmAttributes = 0x0002 <BULK> > wMaxPacketSize = 0x0200 > bInterval = 0x0000 > bRefresh = 0x0000 > bSynchAddress = 0x0000 > > Endpoint 2 > bLength = 0x0007 > bDescriptorType = 0x0005 > bEndpointAddress = 0x0083 <IN> > bmAttributes = 0x0003 <INTERRUPT> > wMaxPacketSize = 0x0002 > bInterval = 0x0008 > bRefresh = 0x0000 > bSynchAddress = 0x0000 > > > > Configuration index 1 > > bLength = 0x0009 > bDescriptorType = 0x0002 > wTotalLength = 0x0050 > bNumInterfaces = 0x0002 > bConfigurationValue = 0x0002 > iConfiguration = 0x0000 <no string> > bmAttributes = 0x00a0 > bMaxPower = 0x0032 > > Interface 0 > bLength = 0x0009 > bDescriptorType = 0x0004 > bInterfaceNumber = 0x0000 > bAlternateSetting = 0x0000 > bNumEndpoints = 0x0001 > bInterfaceClass = 0x0002 > bInterfaceSubClass = 0x0006 > bInterfaceProtocol = 0x0000 > iInterface = 0x0005 <CDC Communications Control> > > Additional Descriptor > > bLength = 0x05 > bDescriptorType = 0x24 > bDescriptorSubType = 0x00 > RAW dump: > 0x00 | 0x05, 0x24, 0x00, 0x10, 0x01 > > > Additional Descriptor > > bLength = 0x05 > bDescriptorType = 0x24 > bDescriptorSubType = 0x06 > RAW dump: > 0x00 | 0x05, 0x24, 0x06, 0x00, 0x01 > > > Additional Descriptor > > bLength = 0x0d > bDescriptorType = 0x24 > bDescriptorSubType = 0x0f > RAW dump: > 0x00 | 0x0d, 0x24, 0x0f, 0x03, 0x00, 0x00, 0x00, 0x00, > 0x08 | 0xea, 0x05, 0x00, 0x00, 0x00 > > > Endpoint 0 > bLength = 0x0007 > bDescriptorType = 0x0005 > bEndpointAddress = 0x0083 <IN> > bmAttributes = 0x0003 <INTERRUPT> > wMaxPacketSize = 0x0010 > bInterval = 0x0008 > bRefresh = 0x0000 > bSynchAddress = 0x0000 > > > Interface 1 > bLength = 0x0009 > bDescriptorType = 0x0004 > bInterfaceNumber = 0x0001 > bAlternateSetting = 0x0000 > bNumEndpoints = 0x0000 > bInterfaceClass = 0x000a > bInterfaceSubClass = 0x0000 > bInterfaceProtocol = 0x0000 > iInterface = 0x0000 <no string> > > > Interface 1 Alt 1 > bLength = 0x0009 > bDescriptorType = 0x0004 > bInterfaceNumber = 0x0001 > bAlternateSetting = 0x0001 > bNumEndpoints = 0x0002 > bInterfaceClass = 0x000a > bInterfaceSubClass = 0x0000 > bInterfaceProtocol = 0x0000 > iInterface = 0x0004 <Ethernet Data> > > Endpoint 0 > bLength = 0x0007 > bDescriptorType = 0x0005 > bEndpointAddress = 0x0081 <IN> > bmAttributes = 0x0002 <BULK> > wMaxPacketSize = 0x0200 > bInterval = 0x0000 > bRefresh = 0x0000 > bSynchAddress = 0x0000 > > Endpoint 1 > bLength = 0x0007 > bDescriptorType = 0x0005 > bEndpointAddress = 0x0002 <OUT> > bmAttributes = 0x0002 <BULK> > wMaxPacketSize = 0x0200 > bInterval = 0x0000 > bRefresh = 0x0000 > bSynchAddress = 0x0000 > > > Unfortunately there is no datasheet available, I quote ``` Due to > company policy, we only release Datasheet to our ODM/OEM (which have > signed a company to company NDA with Realtek).

I contacted with a Linux driver maintainer and asked if he could provide me the data sheet of RTL8152, not surprisingly, he couldn't send me a copy, but he would try to answer my questions. > When looking at the usb trace on Linux with wireshark > (https://rickvanderzwet.nl/svn/personal/freebsd-rtl-driver/linux-trace.pcapng.gz) > I see a "CDC" like packets passing by, the description of the chipset > also hints something in this way: "Supports CDC-ECM". > > > [root@vbsd101 /usr/src]# usbconfig -d ugen1.2 set_config 1 > > [root@vbsd101 /usr/src]# tail -4 /var/log/messages > Feb 5 08:58:12 vbsd101 kernel: cdce0: <CDC Communications Control> on > usbus1 > Feb 5 08:58:12 vbsd101 kernel: ue0: <USB Ethernet> on cdce0 > Feb 5 08:58:12 vbsd101 kernel: ue0: Ethernet address: 64:d1:a3:31:81:80 > Feb 5 08:58:12 vbsd101 devd: Executing '/etc/pccard_ether ue0 start' > > [root@vbsd101 /usr/src]# ifconfig ue0 > ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > ether 64:d1:a3:31:81:80 > inet 192.168.5.200 netmask 0xffffff00 broadcast 192.168.5.255 > nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> > > How-ever there is no traffic possible and also no bulk requests are done. > > > > Looking at the if_rue(4) and the linux r8152.c code, basically I got > this far in porting but yet no working code: > https://rickvanderzwet.nl/svn/personal/freebsd-rtl-driver/ > > There are no bulk out and in packets passing trough, so I am basically > stuck now, not knowing how-to continue this journey.
