[linux-dvb] Extreme small packet loss on Skystar2 rev2.6b

[Alexander Sotnikov <sandworm77@trirema.kiev.ua>]

Hi All

Tests with  1.1.1 (and CVS too) release drivers on   2.4.25 and 2.4.27
I used iperf in udp mode , on smallest payload size   64B  loss is 54%  
on   352B  it is  0% , result doesnt depend on PPS or symbol rate , but 
does depend on CPU in host computer (or chipset?)    also I put same 
Skystar2 on Win2k  machine to  make sire card working properly ,  loss 
was zero on all packet sizes.
weird thing is that ifconfig report right  RX packet counter but  iperf  
on different computer (connected via ether) recieving only fraction of  it.
with twinhan VP1020A in same setup loss was zero on all packet sizes and 
speeds , kernel and/or DVB drv versions and host computers.

how much interupts SS2 should generate? Because mine gen around ~450 on 
30Msym full load no mater what packet size is.
what to do?  where to look?

Thanks
