I was not aware, that there is a (big) difference between 8139C and 8139C+

lspci shows my NIC as this:
00:09.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139 (rev 10)

while /proc/pci tells this:
PCI devices found:
  Bus  0, device   9, function  0:
    Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 16).
      IRQ 10.
      Master Capable.  Latency=64.  Min Gnt=32.Max Lat=64.
      I/O at 0x1c00 [0x1cff].
      Non-prefetchable 32 bit memory at 0x10000000 [0x100000ff].

Which is the correct/best driver for that NIC?
