[realtek] Oversized Ethernet frame

[Howard Cheng]

Hi,

  I have scanned through the mailing list archive and I don't seem to
find any definitive resolution on this one.  I am getting

Oct 30 15:10:41 scg7 kernel: eth0: Oversized Ethernet frame, status cccccccc! 
Oct 30 15:10:41 scg7 kernel: eth0: Abnormal interrupt, status 00000021. 

every once in a while (when traffic is high), and I have to manually
ifdown and ifup the interface.

Some information about my network card:

Index #1: Found a SMC1211TX EZCard 10/100 (RealTek RTL8139) adapter at 0xb000.
The RealTek chip appears to be active, so some registers will not be read.
To see all register values use the '-f' flag.

Sorry for including so much.  Not sure what you will need.  I am
running Linux 2.2.16-3 and Red Hat 6.2.  Any help would be deeply
appreciated.
