I sometimes get the following error message using a RealTek 8169S Single-chip
Gigabit Ethernet card:
re0: discard oversize frame (ether type 800 flags 3 len 1514 > max 1506)

This happens at seemingly random times. 

root ~ # ifconfig re0
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1492
        options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
        inet 192.68.0.2 netmask 0xffffff00 broadcast 192.68.0.255
        ether 00:08:54:36:f2:2f
        media: Ethernet autoselect (10baseT/UTP)
        status: active

Notice that 1514-1506=1500-1492.
Is this something to worry about?
Thanks in advance.
