net: socionext: netsec: fix xdp stats accounting
Increment netdev rx counters even for XDP_DROP verdict. Report even tx bytes for xdp buffers (TYPE_NETSEC_XDP_TX or TYPE_NETSEC_XDP_NDO). Moreover account pending buffer length in netsec_xdp_queue_one as it is done for skb counterpart Tested-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Reviewed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S.
