Subject: [PATCH 090/122] net/ipn3ke: fix xstats get return if xstats is null

|
Many user (e.g. telemetry) invokes rte_eth_xstats_get(port_id, NULL, 0)
|
|
to retrieve the required number of elements, but currently ipn3ke PMD
|
|
returns zero when xstats is null.
|
|
|
|
Dedicated check for xstats vs null is not required, since ethdev layer
|
|
guarantees that it may be null only if number of entries n is 0 (which
|
|
is definitely smaller than total xstats count).
|
