* Name: cs89x0_initialize
*
* Description:
* Initialize the Ethernet driver
*
* Parameters:
* impl - decribes the implementation of the cs89x00 implementation.
* This reference is retained so so must remain stable throughout the
* life of the driver instance.
* devno - Identifies the device number. This must be a number between
* zero CONFIG_CS89x0_NINTERFACES and the same devno must not be
* initialized twice. The associated network device will be referred
* to with the name "eth" followed by this number (eth0, eth1, etc).
*
* Returned Value:
* OK on success; Negated errno on failure.
*
* Assumptions:
