Bingo.

Can you display the whole descriptor entry (opts1 and opts2) and its
index (cur_rx) when abnormal packets are detected ?
We can always check the packet size but I'd welcome some more specific
pattern in the remaining bits of the descriptor.

Btw, you may try to revert aee77e4accbeb2c86b1d294cd84fec4a12dde3bd
("r8169: use unlimited DMA burst for TX") and see if it changes the
Rx / Tx balance. It would only be a bandaid though.
