net: enetc: change the statistics of ring to unsigned long type
The statistics of the ring are all unsigned int type, so the statistics
will overflow quickly under heavy traffic. In addition, the statistics
of struct net_device_stats are obtained from struct enetc_ring_stats,
but the statistics of net_device_stats are unsigned long type. So it is
better to keep the statistics types consistent in these two structures.
Considering these two factors, and the fact that both LS1028A and i.MX95
are arm64 architecture, the statistics of enetc_ring_stats are changed
to unsigned long type. Note that unsigned int and unsigned long are the
same thing on some systems, and on such systems there is no overflow
advantage of one over the other.
