Here's how Packet Capture is an effective networking tool for IT professionals to obtain complete information about their network traffic.
dnl if you use AC_TRY_COMPILE in a macro, stick AC_PROG_CC at the dnl beginning of the macro, even if the macro itself calls AC_PROG_CC. dnl See the "Prerequisite Macros" and "Expanded Before Required" sections dnl in the Autoconf documentation. ...

In today's episode of "I hate the Linux networking stack", I set up a Debian 11.3.0 VM, with a 5.10.0-13-amd64 kernel, built top-of-the-main branch libpcap and tcpdump, set up two layers of VLAN interface (boring packet statistics removed): ens33: flags=4163<UP,BROADCAST,RUNNING...
so the regular networking stack can't send to it), but is instead being sent by writing to a PF_PACKET socket, it might be that looping back packets sent on a PF_PACKET socket to the PF_PACKET socket on which the capture is being done isn't resulting in the right protocol being pro...
