Validate the value of the -l argument (packet length) against the MTU of the netmap port. In case the netmap port does not refer to a physical interface (e.g. VALE port or pipe), then the netmap buffer size is used as MTU. This change also sets a better default value for the -M option, so that pkt-gen uses the largest possible fragments in case of multi-slot packets.

$FreeBSD$ This directory tree contains tools used for the maintenance and testing of FreeBSD. There is no toplevel Makefile structure since these tools are not meant to be built as part of the standard system, though there may be individual Makefiles in some of the subdirs.
