Hi,

rte_pcapng_copy() is called with rte_get_tsc_cycles().
And, if pcapng isn't initialized, pcapng_init() is called.
rte_get_tsc_cyles() is called during pcapng_init for base time.
But, cycles on pcapng_init() is later cycle than parameter of rte_pcapng_co=
py()
in this case.
So, delta value of pcapng_tsc_to_ns() will be negative value.
But, delta value type is uint64_t.
It will cause incorrect timestamp.
Maybe, I'm thinking that pcapng_init() should be called before
rte_pcapng_copy().
