nat: configurable handoff frame queue size
Make number of worker handoff frame queue elements configurable as
a set nat frame-queue-nelts command. The default value is 64 which
is the same value that was previously hard-coded. The idea is that
allowing larger values can be useful in some cases, to avoid
congestion drops. Also add nat_set_fq_options API support and a
corresponding test case.
Type: improvement
