[Xenomai-help] Xenomai and Libpcap

[Benjamin Biegel <biegel@domain.hid>]

Hej

I have a question regarding the use of Libpcap together with Xenomai. 
The Libpcap library provides the ability to capture Ethernet frames with 
my NIC in promiscuous mode + time stamp the received frames on Ethernet 
level (through the clock of the NIC).

My question is this: How do i set up an Xenomai real-time environment 
that makes the time-stamping very accurate. How do I have influence on 
when pcap is scheduled? How do I make sure pcap is not preempted by the OS?

Thanks for any guidance on this point :)
