How to send a big tso packet using tcpreplay or other tools on linux

Question

I want to send a big tso packet in a pcap file using tcpreplay. this pcap file was catpured in the same nic interface. But when using tcpreplay to send this pcap on the same nic interface, it reported message too long.

The purpose of this case is to test the tso flow, I want to emulate the tso flow, OS send a big tcp packet then the nic will segment this big tcp packet to many small tcp packets.

Do you have suggestion for this flow? Thanks!

The following is the command and the log:

tcpreplay --loop=10 -i br0 tcp.big.pcap processing file: tcp.big.pcap Warning: Unable to send packet: Error with PF_PACKET send() [91]: Message too long (errno = 90)
