I used the same dump so pcap_sendpacket() failed on the same packet. It was TCP packet with size ~15000 bytes. Seems WinPCap cannot send such large packets. Do you know the reason or any workaround for this?

I'm replaying traffic captured by tshark to .cap file. I read a packet from file and send it to specific network interface by pcap_sendpacket() (actually by pypcap Python wrapper) in loop. On two different machines first one with Win7 SP1 x64 and the second one with Win2k3 SP2 x86 WinPCap always fails sending 1960th packet. What does this magic number means?
