eepro100: Improve support for different devices
* Add device properties (size of statistical data, extended tcb support) to EEPRO100State and set these values for the different devices. * Fix PCI configuration for existing devices. * Add initialisation code for missing devices. * Remove function device_supports_eTxCB. It is no longer needed. * Fix dump of statistical data. It now respects the real size of the statistical data. An endianess issue was fixed here, too. * CU_SHOWSTATS, CU_DUMPSTATS now write a completion value after the statistical data. There is no need to keep this value in eepro100_stats_t, so member "complete" could be removed. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
