This Kingston KNE110TX appears to have problems dealing with large amounts of ethernet data. The system will boot, run ntpdate, can do basic ping/nslookup/etc. but heavier traffic (nfs, large pings, etc.) will give lots of:
tlp0: discarding oversize frame (len=16379)
The size is always the same.
>How-To-Repeat:
ping is the easiest way to see this:
performa6400# ping -s 8192 192.168.1.63
PING aelfric (192.168.1.63): 8192 data bytes
8200 bytes from 192.168.1.63: icmp_seq=0 ttl=64 time=7.210900 ms
