List,

My e1000 is built as default and MTU=1500. After e1000.ko is insmoded, "ping -c 
1 -s 1400 www.google.com" works fine.  But "ping -c 1 -s 1600 www.google.com" 
does not work.

I check e1000_main.c and see:

skb->data_len = 0 and skb_shinfo(skb)->gso_size = 0.

I see skb buffer only has partial packet and expect to see none zero 
skb->data_len. But looks like frag feature in kernel is not enabled.
