libpcap0.8-dev 1.9.1-3 (s390x binary) in ubuntu focal

 Headers, static libraries, and documentation for the libpcap library.
 .
 libpcap (Packet CAPture) provides a portable framework for low-level
 network monitoring. Applications include network statistics
 collection, security monitoring, network debugging, etc.
 .
 Since almost every system vendor provides a different interface for
 packet capture, and since there are several tools that require this
 functionality, the libpcap authors created this system-independent API
 to ease in porting and to alleviate the need for several
 system-dependent packet capture modules in each application.
