@jiangjiongyu did you see my comments? do you have time to address them?

[bitFiedler]

Is this patch needed to support linux cooked capture v2 in live capture into file?
Because I thought libpcap das that and pcap++ is only a c++ wrapper.

I tried to understand why tcpdump creates pcap files with linux cooked capture v2 and pcap++ don't.

@bitFiedler this PR will support SLLv2 which is currently not a supported protocol. This means that packets in a pcap file with this link type won't be parsed correctly and will contain only one layer which is the generic PayloadLayer

@jiangjiongyu did you see my recent comments? Do you think you'll have time to fix the PR so we can merge it?

@jiangjiongyu please fix the tests as they are failing:

I already check the test file path.Why those test can't pass?

@jiangjiongyu you fixed the previous issue, but now there are other problems that need fixing:

• Visual Studio build fails https://github.com/seladb/PcapPlusPlus/actions/runs/5586651059/jobs/10228625110. This is because you need to add #include "SystemUtils.h" in Sll2Tests.cpp. You can see how we add it in other test files
• pre-commit issue - there is no newline at the end of the file Sll2Tests.cpp: https://github.com/seladb/PcapPlusPlus/actions/runs/5586651059/jobs/10228624983
• Doxygen documentation error: https://cirrus-ci.com/task/6678788340187136 :
  Generating docs for co/tmp/cirrus-ci-build/Packet++/header/Sll2Layer.h:165: error: argument 'arphrd' of command @param is not found in the argument list of pcpp::Sll2Layer::setArphrdType(uint16_t arphrdType)
