CheckARPHeader -- Click element; checks ARP header
CheckARPHeader([OFFSET, keywords OFFSET, VERBOSE, DETAILS])
Ports: 1 input, 1-2 outputs
Processing: agnostic, but output 1 is push
Package: ethernet (core)
Input packets should have ARP headers starting OFFSET bytes in. Default OFFSET is zero. Checks that the packet's length is reasonable. CheckARPHeader emits valid packets on output 0. Invalid packets are pushed out on output 1, unless output 1 was unused; if so, drops invalid packets. CheckARPHeader prints a message to the console the first time it encounters an incorrect ARP packet (but see VERBOSE below). Keyword arguments are:
drop_detailshandler. False by default.
