+ * SMSC LAN9xxx devices (http://www.smsc.com/)
+ *
+ * The LAN9500 & LAN9500A devices are stand-alone USB to Ethernet chips that
+ * support USB 2.0 and 10/100 Mbps Ethernet.
+ *
+ * The LAN951x devices are an integrated USB hub and USB to Ethernet adapter.
+ * The driver only covers the Ethernet part, the standard USB hub driver
+ * supports the hub part.
+ *
+ * This driver is closely modelled on the Linux driver written and copyrighted
+ * by SMSC.
+ *
+ * H/W TCP & UDP Checksum Offloading
+ * ---------------------------------
+ * The chip supports both tx and rx offloading of UDP & TCP checksums, this
+ * feature can be dynamically enabled/disabled.
+ *
+ * RX checksuming is performed across bytes after the IPv4 header to the end of
+ * the Ethernet frame, this means if the frame is padded with non-zero values
+ * the H/W checksum will be incorrect, however the rx code compensates for this.
+ *
+ * TX checksuming is more complicated, the device requires a special header to
+ * be prefixed onto the start of the frame which indicates the start and end
+ * positions of the UDP or TCP frame. This requires the driver to manually
+ * go through the packet data and decode the headers prior to sending.
+ * On Linux they generally provide cues to the location of the csum and the
+ * area to calculate it over, on FreeBSD we seem to have to do it all ourselves,
+ * hence this is not as optimal and therefore h/w tX checksum is currently not
+ * implemented.
