r8169: merge with version 6.001.00 of Realtek's r8169 driver
- new identifier for the 8110SCe - the PCI latency timer is set unconditionally. This part is identical in Realtek's r8168 (8.001.00) and r8101 (1.001.00) - initialization of the cache line size register is for the 8169s only - more magic in rtl_hw_start_8169 - it is not possible to factor out the setting of the the irq event mask with the 8168 and the 8101 any more. Pushed it into the hw_start handler. - rtl_set_rx_tx_config_registers() and write to the ChipCmd register are issued identically for the whole 8169/8110 family: the 8110SCd/8110SCe are handled the same way - work around for AMD platform. Some registers definitions in Realtek's driver are let aside for later. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Cc: Edward Hsu <edward_hsu@realtek.com.tw>
