 Hi,
 
 I just wanted to add that I cannot reproduce this problem on my Realtek
 DGE-528T which is another card supported by re(4).
 
 By reading some more of the code, I think that the crong checksum flag is set
 when receiving the packet, to be specific in sys/dev/ic/rtl8169.c in
 re_rxeof(), at the end of the function. What seems a bit odd to me is that the
 protocol family is not checked, which is done in other drivers. Instead, the
 flags for IPv4 are just added, if the hardware says so. Probably the cards
 affected by this bug *do* say so.
 
 I will further debug this in one or two weeks, when I get another mainboard
 with this chip, if no one has this chip somewhere else.
 
 Best regards,
 Michael
