Assuming pkts is the plural of pkt, I think it would
be more intuitive to name this structure pkt_stats.

I think the commends above would be better placed next to
n_offload_packets and n_offload_bytes below.

It looks like the above two lines appear in both arms of the if conditional.
If so, could they be moved outside the if conditional?

I think this would be better worded something like this:

If \fB\-m\fR or \fB\-\-more\fR are specified then also list statistics for
offloaded packets and bytes, which are a subset of the total packets and
bytes.

Also, I wonder if it would be better to name the option something
like --offload-stats, as --more is rather generic and may end up being
a name we regret choosing.

Likewise, I wonder if it would be clearer to rename 'verbosity'
as something like 'offload_stats".
