The SMSC LAN95xx has an integrated USB Hub and is technically a compound device. Here we instead use the vendor Id and product Id of the vendor specific class device attached to the hub that is the device we actually need to communicate with. The hub will be detected and bound by the default USB Hub driver when it is enumerated by the USB core.

SMSC95XX burst cap SMSC95XX_BURST_CAP_*

When multiple Ethernet frames per USB bulk transfer are enabled, this register must be set by software to specify the maximum number of USB (not networking!) packets the hardware will provide in a single Bulk In transfer.
This register is ignored if HW_CONFIG_MEF is not set. Otherwise, this must be set to at least 5, which represents a maximum of 5 * 512 = 2560 bytes of data per transfer from the high speed Bulk In endpoint.

SMSC95XX bulk in delay SMSC95XX_BULK_IN_DELAY_*

The low 16 bits of this register contain a value that indicates the maximum amount of time the hardware waits for additional packets before responding to a Bulk In request once a packet has been received. From experiment, the time is specified on a linear scale where each unit is approximately 17 nanoseconds. The default value in this register after reset is 0x800 which indicates a delay of about 34.8 microseconds, assuming that the scale is 0-based. SMSC's Linux driver changes this to 0x2000, or a delay of about 139 microseconds.
The value in this register no effect if HW_CONFIG_MEF is not set in the HW_CONFIG register.

`SMSC95XX_MAC_CONTROL_RX_ENABLE = $00000004;`	Receive enabled. 1 to enable/0 to disable.

SMSC95XX MAC address SMSC95XX_MAC_ADDRESS_*

This contains the high 2 bytes of the MAC address used by the device, stored in little endian order. As they are not part of the MAC address, the hardware ignores the values written to the upper 2 bytes of this register and always reads them as 0.
Software can change the MAC address used by the device by writing to the MAC_ADDRESS_HIGH and MAC_ADDRESS_LOW registers, and it can retrieve the current MAC address by reading them. On reset, the device will read its MAC address from the EEPROM if one is attached; otherwise it will set its MAC address to 0xFFFFFFFFFFFF.

`SMSC95XX_MAC_ADDRESS_HIGH = $104;`
This contains the low 4 bytes of the MAC address used by the device, stored in little endian order. See MAC_ADDRESS_HIGH.
