Expose FEC Counters via Standard Ethtool Interface

[ConnectX-4 and above] Exposed Ethtool counters which report FEC (forward error correction) statistics via the 'ethtool -I --show-fec ethX' command.

• fc_fec_corrected_blocks_laneX

• rs_fec_corrected_blocks

• fc_fec_uncorrectable_blocks_laneX

• rs_fec_uncorrectable_blocks

• phy_corrected_bitz

Ethtool CQE Mode Control

[ConnectX-4 and above] Replaced the vendor-specific Ethtool API (priv-flag) with a standard Ethtool API (replaced 'ethtool --set-priv-flags ethX rx_cqe_moder on/off tx_cqe_moder on/off' with 'ethtool -C ethX cqe-mode-rx on/off cqe-mode-tx on/off').

This decreases the amount of vendor-specific configurations and aligns mlx5 driver with the upstream Ethtool API.

Reduce Memory Consumption

[ConnectX-4 and above] Reduced memory consumption.

Previously, several hardware/memory resources were pre-allocated per NetDev to serve a prefixed maximum allowed value. Now, the actual maximum is used instead of the prefixed theoretical maximum and resources are allocated on demand, improving memory consumption.

Dumping Software Steering Information

[ConnectX-5 and above] Extended mlx5 debugfs support to present Software Steering resources: dr_domain including its tables, matchers, and rules.
The interface is read-only. While dump is being presented, new steering rules cannot be inserted/deleted.
This allows to see the existing steering configuration and to be able to debug steering issues.
