pcap_geterr() returns the error text pertaining to the last pcap
library error. NOTE: the pointer it returns will no longer point to
a valid error message string after the pcap_t passed to it is closed;
you must use or copy the string before closing the pcap_t.
pcap_perror() prints the text of the last pcap library error on
stderr, prefixed by prefix.
