packet loss when read .pcap

[kuku000]

Thx for your powerful toolkit!!!
I encountered a problem:
The problem is that I collected 425 packets using a Raspberry Pi. When I opened them with Wireshark, the packet count was 425. It was also 425 when I used MATLAB (provided by Nexmon). However, when extracting the packets using csikit, only 300 packets were extracted.
Pictures:


1 rx ,1 tx ,80MHz

Matlab result:

I find the problem happen here, this part is to drop the same seq_no packets ?

I am confused that why need to do it🤔
