No problem. It would have been easier with a decoded output of the register
dump though (see Lennert dump below).
Lines prefixed by '>' come from Realtek's driver. I have outlined the
differences which seem relevant to me.

If ChipCmd is not set, the driver will hardly work.
Lennert, your dump was taken while the kernel driver was down, right ?

RxFIFOOver = 0x40,
LinkChg = 0x20,
RxOverflow = 0x10,
TxErr = 0x08,
TxOK = 0x04,
RxErr = 0x02,
RxOK = 0x01,
0x0000 is typical of rtl8169_irq_mask_and_ack().
The device seems down.

Realtek's driver uses an unlimited DMA burst (7) instead
of 1024 (6, see TX_DMA_BURST). Probably harmless.

These bit should be set by the kernel driver through
rtl8169_set_rx_mode() when the device is brought up
The exact same value would require to replace (in rtl8169_set_rx_mode):
rx_mode = AcceptBroadcast | AcceptMyPhys;
by:
rx_mode = AcceptBroadcast | AcceptMulticast | AcceptMyPhys;
