nvethernet: ethtool: add support for stats

Browse Source 
These stats are read from MAC HW RMON counters as well as SW controlled
control from Core and DMA path.
ethtool -S <interface> is used to get statistics.
There are 3 stats
1) ether_mmc_counters: EQOS HW counters
2) ether_xtra_stat_counters: SW counters from osi/core
3) ether_xtra_dma_stat_counters: SW counters from osi/dma
