Hello, David! 

> Your oscilloscope is connected to the physical Ethernet cable, correct?

Yes, that is wright.	

> By "delay" you mean what? Please define your "delay".

I guess it is my mistake with word of 'delay'. Wireshark can show time since previous packet was capture,
from the view menu, submenu time format.. So that 'time' has huge spread. And those 'delays' i mean that
is a time from previous packet to next one and etc. 

I've see some post about time stamping problems, so i've try to do the following:

using Winpcap examples, i've write a small test program, when pcap_next_ex return some packet i've send
the same (or custom packet) back using pcap_sendpacket and using oscilloscope discover that my packets
on the RX+/- line (TX+/- for PC)  goes with some delays (wright word for now). 
David, can You please see this Wireshark log: http://www.winpcap.org/pipermail/winpcap-users/attachments/20100622/794818cb/attachment-0001.zip

It is just example, i've tried to use some others MAC's and different packets size, the same result :(

With many thanks and best wishes, Alimjan Kuramshin..
