net: stmmac: Add EST errors into ethtool statistic
Below EST errors are added into ethtool statistic: 1) Constant Gate Control Error (CGCE): The counter "mtl_est_cgce" increases everytime CGCE interrupt is triggered. 2) Head-of-Line Blocking due to Scheduling (HLBS): The counter "mtl_est_hlbs" increases everytime HLBS interrupt is triggered. 3) Head-of-Line Blocking due to Frame Size (HLBF): The counter "mtl_est_hlbf" increases everytime HLBF interrupt is triggered. 4) Base Time Register error (BTRE): The counter "mtl_est_btre" increases everytime BTRE interrupt is triggered but BTRL not reaches maximum value of 15. 5) Base Time Register Error Loop Count (BTRL) reaches maximum value: The counter "mtl_est_btrlm" increases everytime BTRE interrupt is triggered and BTRL value reaches maximum value of 15. Please refer to MTL_EST_STATUS register in DesignWare Cores Ethernet Quality-of-Service Databook for more detail explanation.
