Hello, David! Thanks for reply..

Well, i'm trying to make an ethernet connection between my laptop, it's Asus G1S(Intel Core 2 2.2 Ghz RAM 2Gb, Realtek 8111B/8168B) 
with Windows SP SP3/Windows Vista/Windows7(i've got the same result on the all of them :( )
installed, and my custom device with an ethernet controller. So, when my device send data to the PC, i'm using the Wireshark to
capture incoming stream, and found those delays, using oscilloscope on TX+/- line i don't see any delays between the packets,
everything just fine. And delay is very strange i guess, for example(delays in us): .. .. 45 46 44 48 49 1200 44 48 44 46 49 42 50 1530 ..
and number of 'normal' delay between packets is very vary as delay itself, i can receive 200 packet with delay of 40-60 us and then i've got
huge timeout 1-3 ms, some times much greater, then 1000 packets normal and then again delay, so i can't see no logic with it.
From this point my question is: is it possible to archive stable receive with WinPCAP  during long period of transfer, i mean stable capture interval?! 

Thanks, bye bye..

P.S. i hope u can forgive my miss types and ugly english language and can understand my. And again many many thanks for Your time and answers!!

P.P.S. i'm using winpcap 4.1.2 and wireshark 1.4.0, well, i try many of them :(
