Implement following ethtool callback function:
.get_ringparam
.set_ringparam
These callbacks allow users to utilize ethtool for detailed
queue depth configuration and monitoring.

Add PF/VF statistics functions in TX and RX processing.
Implement following ethtool callback function:
.get_sset_count
.get_ethtool_stats
.get_strings
.get_eth_phy_stats
.get_eth_mac_stats
.get_eth_ctrl_stats
.get_rmon_stats
.get_pause_stats
These callbacks allow users to utilize ethtool for detailed
TX and RX netdev stats monitoring.

Implement following ethtool callback function:
.get_rxnfc
.set_rxnfc
.get_channels
.set_channels
.get_rxfh_indir_size
.get_rxfh_key_size

These callbacks allow users to utilize ethtool for detailed
RSS parameters configuration and monitoring.
